UVP Chromato-Vue® C-65 Observing Cabinet
"the most capable and versatile of the ultraviolet enclosures"
The UVP Chromato-Vue® C-65 Observing Cabinet is the most capable and versatile of the ultraviolet enclosures in the UVP products line. Each of these observing cabinets bring convenience and safety to an ultraviolet observing or imaging session. The cabinets are self contained ultraviolet laboratories where a sample may be introduced through the curtain flaps at the front and into the enclosure for safe visual observing or for imaging with a camera through the UV-filtered observing port. This is similar in concept to the photographic light box, but optimized for ultraviolet applicatons. The C-65 incorporates several features that make this our top choice of observing cabinet, particularly well suited for classroom educational applications, and for studies in a laboratory or field station - wherever AC power is available.

The aspects that distinguish the C-65 from other UVP cabinets have to do with its a) versatility, b) its broad range of UV energies that can be applied to the subject of a study, c) the directions from which these energies can simultaneously be applied:
- This cabinet offers the user the choice of attaching either one or two optional UV highly capable EL Series 8 watt lamps as the cabinet incorporates two outlets and control switches to power the optional EL lamps.
- The two EL lamps can both be either an identical 254, or 302, or a 365 nm source thereby allowing the user to apply massive UV emissions (mW/cm2 or µW/cm2) of any one wavelength to the subject in the cabinet.
- The EL lamps may be a mix of 254 and or 302 and or 365 nm sources thereby allowing the user to apply high UV emissions of any one or two wavelengths.
- The EL lamps may be a mix of spectrum sources (254 and or 302 and or 365 nm) thereby allowing the user to apply useful UV emissions of any one or two wavelengths simultaneously.
- Two EL Model UVLMS-38 lamps may be attached to provide 254 and or 302 and or 365 nm from one or both front and or rear access ports at the top of the cabinet thereby allowing the user to study the sample in of any of three wavelengths with either or both of these illuminating simultaneously.
- all UVP cabinets afford the user the choice of removing the bottom panel and either placing the cabinet over a subject of study or onto a compatible Transilluminator. This UV backlighting capability combined with coverage from all angles from above can totally bathe a subject with UV - a vital consideration for some germicidal applications.
The versatility of the C-65 is due to the provision of two sample access ports spanning the width of the C-65 cabinet and along either side of the center that houses the white light lamps, switches and wiring. The C-65 is delivered with one of the two ports open so that you can simply set any 8 watt EL Series lamp over this port; the lamp plugs into the AC socket to the right side of the observing port. The second port is provided with a metal cover over it, to use this port with a second 8 watt EL Series lamp simply remove the four Phillips head screws and nuts that hold the plate over the port.

C-65 AC Power Management is well thought out. The C-65 incorporates a male IEC 320-C14 plug receptacle under the top panel, that is powered by a wall outlet/mains via a standard AC power cord. This may be the eight foot long NEMA 5 to IEC 320-C13 cord provided the USA for example; the appropriate power cord is provided only for orders sent to within the USA. For orders going to overseas then the recipient of the system would need to buy locally an AC power cord with the a common IEC 320-C13-style female connector and with the appropriate mains male connector for their country at the other end of the cable.
The top panel of the C-65 has a small channel molded at the left rear corner, this allows routing the AC power cable from the IEC 320-C14 socket out of the rear of the cabinet, and onto the wall socket. The panel may remain connect do AC power since the top panel incorporates an illuminated on-off main power rocker style switch. Alongside this panel is the switch controlling the white light lamp built into the cabinet.
To conveniently supply AC power to the EL Series lamp(s) the C-65 provides two switched IEC C13 sockets at the top panel, just to the right of the observation port. The illuminated rocker switch to power both outlets on or off is the main power switch atop the left side panel.

Each EL Series lamp provided by Company Seven is made with a short AC power cord attached, and with a IEC 320-C14 male plug . In standalone use this short section of AC cord remains connected to a provided conventional eight foot long power cord and AC plug, just like that included the C-65 cabinet. But for use with the C-65 cabinet the eight foot long AC power cord is not used, and the remaining short AC power cord connects to either of two switched IEC 320-C13 AC sockets atop the C-65 cabinet.
With AC power established to the C-65 turn on the Main Power rocker switch (top left of the observation port) to energize the switch for the built-in white light and power on both AC sockets atop the C-65 cabinet. Push the rocker switch just forward of the Main Power to turn on the white light to clearly see the contents of the cabinet. To turn on the UV lamp(s) turn off the white light switch, then control the lamp from its provided power rocker switch. The multi-wavelength EL Series lamps will have a second rocker switch to select wavelength.
The C-65 allows the added benefit of being able to simultaneously power-on the internal white light and any attached UVP lamps. So one can bathe the sample in white light to see its natural appearance, then turn off the white light while switching over to UV to stimulate fluorescence, then turn the white light on again even while the UV lamps are on:

C-65 Construction the cabinet housing is made of a durable and UV resistant molded plastic designed to keep all UV inside the cabinet; there is no glare or shine out of any area other than the observing port. The interior and exterior panels of the cabinet are black, and even with all UV lamps on there is no fluorescence of any component. The removable bottom panel of the cabinet is a black finished aluminum plate. The set is quite lightweight and manageable, even with two EL Series Lamps attached the set weighs no more than 15 lbs 3.5 oz. (6.92 kg).

Here the cabinet housed only a white sheet of paper, hence a bright reflectance that saturated our pocket camera giving too white an appearance.

The viewing and imaging port is molded of plastic to match the upper and lower sections of the C-65. To insure safe observing sessions the port is provided with a visually transparent contrast control filter that will block all UV light from exiting the cabinet while also enhancing the visual experience. This is also a convenient port to take pictures through. For comfort a molded rubber face guard provides a convenient reference for inexperienced observers, even those wearing spectacles. The rubber face guard slips over the port panel, and this assembly may be easily removed for cleaning or replacement.
For imaging applications (not for direct viewing without safety precautions) the contrast control filter or the entire top panel with the filter and face guard can be removed to allow placement of a camera over the port to shoot the contents of the cabinet at highest possible resolutions. When working around a cabinet without the filter in place Company Seven urges the use of protective eyewear, and even full coverage (gloves, long sleeves, etc.) when working at 254nm. Cameras placed over the open port should be supported by a tripod or other fixturing, with the camera set up and focused on target under safe white light, then the aperture/shutter speed and actuation should be controlled remotely or on timer, so that the user does not have to expose themselves to the UV light.
Some of our customers employ a Transilluminator (such as models we sell to illuminate gels) as back-lighting. UVP observing cabinets feature a removable bottom panel so that a Transilluminator may be attached, or this may be built into custom cabinet installations. The Transilluminator would be connected to AC power by its own AC cord.

WARNING Infrared and ultraviolet wavelengths are invisible to the human eye yet these electromagnetic waves bear energy and other information. So any structure that absorbs the light can be damaged by this energy; note how sunlight exposure tans the skin while prolonged exposure fades or breaks down materials. The photons of shorter wavelength carry greater energy therefore, these have the greater potential for causing biological damage. These wavelengths can penetrate the eye or skin cells and can produce heating and energy related biological changes that will modify or destroy cellular DNA; this is among the reasons why some UV light sources are used for germicidal (sterilizing) applications.
As amazing as it can be to explore the ultraviolet spectrum, this is not child’s play! The UVP observing cabinets are designed so that when operators following proper procedures then there is no risk to the users, and no other safety equipment need be worn by the operator or other observers. In order to keep the protections designed into these cabinets intact:
- Never reach into any UV observing cabinet with the UV lamp on - turn off the lamp before reaching into the cabinet.
- Do not allow immature persons to operate the observing cabinet without trained adult supervision.
- Before removing the top panel or the observing port of a cabinet turn off the Main Power Switch AND disconnect the main AC power cable.
- Do not operate the cabinet with any component (port cover, contrast control filter, etc.) intact and in place.
For a good overview of working in the UV and explanations of proper precautions consult Ultraviolet Spectrum Primer, the illustrated article by Company Seven explaining the ultraviolet (UV) spectrum as it applies to photographing or imaging objects in the UV and about observing fluorescence, phosphorescence, and tenebrescence. The article explains the different portions UV spectrum including UV-A (long wave), UV-B (mid) and UV-C (short wave). This also goes into a discussion of imaging gear including lenses, films and filters. Then refer to our article Ultraviolet Personal Safety Gear.
