Everything is Healing Nicely? Ultraviolet Camcorder Will Tell

May 3, 2006 - Oculus Photonics LLP, a joint venture by Taylor Consulting Services and Dr. Austin Richards, has announced the release of its new near-Ultraviolet UVCorder. The UVCorder uses the Active Interface Shoe of a Sony Camcorder to power the ultraviolet camera module (UVM).

Side-by-side comparisons of images in visible light and UV light.

In addition to full close, it has a 16 mm focal length uncoated glass lens with an adjustable iris range from f/1.6 to f/16. Customized lens lengths of 25 mm and 55 mm as well as alternate filters can be purchased from Oculus Photonics LLP at an additional cost.

The UVM mount contains a silicon CCD camera with enhanced ultraviolet response, a peak response of 370nm, and a general range of 300-400nm. This lens has a special filter that simultaneously rejects both visible and infrared light from reaching the sensor; the UVCorder works well for scenes with UV illumination at levels which are lower than IR or visible light. The UVCorder captures video and still images to MiniDV tape and Memory Stick, respectively, and has an approximate 3 hour battery life per charge when using the ultraviolet camera module. For capture, it uses a Sony DCR-HC65 (Review, Specs, $569), which takes advantage of the 3.5 inch LCD screen. As well as the standard Sony benefits, such as ease of use and simplicity, this camcorder offers a hot shoe which can power the UVCorder module. Unfortunately, because the shoe is a Sony-proprietary fit, the UVcorder cannot be connected to any other camcorder.

There are limits to the UVcorder. Still images may have a tendency to display jagged edges, due to their frame grab technology’s struggle with interlaced video fields. Also, the UVcorder cannot display both UV and standard video at the same time. For simultaneous side-by-side comparisons, a second camcorder is needed. Additionally this camcorder has not been CE certified, although Oculus Photonics LLP claims the likelihood of electromagnetic interference is minimal. Dr Richards stated that a CE rating will be applied for if a specific requirement necessitates it.

The UVcorder is targeted at a small but viable market. Potential consumer include the forensic, art conservation, biological, industrial surface inspection, and dermatological fields. The UVCorder package retails for $4995, and includes the UVCorder module, a Sony DCR-HC65, a heavy-duty battery, a Pelican carrying case, and a near-UV LED light source for illumination.
