The Nikon UV-105 is a high performance lens that was developed for specialized multispectral applications in the ultraviolet (UV), visible, and infrared portions of the spectrum. The lens was originally envisioned for uses including law enforcement forensic work (popularized by recent television shows), industrial and biomedical applications, as well as uses by artists and the more enthusiastic amateur. This lens became the preferred choice for work in other areas of forensics too including art research (authenticating and restoration for example), medical studies including dermatology, chemical analysis, plasma research, combustion and electric discharge studies, agriculture, environmental monitoring, mineralogy, surveillance, OEM, manufacturing and process control. This remains the most desired UV lens among the more dedicated amateurs who seek to explore the world that is otherwise invisible to the eye.

While it’s high resolution and transmission deep into the UV most distinguishes the UV-105 from most other lenses, this is also a superb performer in the visible (VIS) and into infrared (IR) portions of the spectrum too.

Instead of quartz glass, the glass necessary to transmit ultraviolet wavelengths is more akin to the gem mineral apatite. The UV-Nikkor uses phosphate glass with a transition wavelength of 220nm, allowing full bandpass of longwave ultraviolet and even some shortwave. This type of lens is only necessary for certain very specific scientific recording purposes, and is very expensive. The only other manufacturer of a UV transmitting lens for an SLR is Carl Zeiss, for Hasselblad cameras. 

Introduced in 1984. This 6 elements in 5 groups Nikkor 105mm f/4.5 UV lens with an Ai-S mount was supplied with standard accessories which include a Gelatin Filter Holder AF-1 and UR-2 as well as a deeply tinted square-sized UV Transmission Filter. This lens includes a Photodiox Nikon to Canon EOS mount adapter and the original cylindrical leather lens case.
