Without either filter, both ultraviolet and visible light are captured, which causes reduced contrast.
Use of an ultraviolet transmission filter allows capturing of only the components in the ultraviolet region.
Use of an ultraviolet cutting filter allows capturing of only the visible light components from scattered light.

- In 1993, the International Electrotechnical Commission (IEC) made effective IEC 825-1, a standard concerning the safety of laser products, the scope of which includes LEDs. Subsequently, relaxation of provisions was considered for diffusive light sources and IEC 60825-1 Edition 1.1 of 1998 introduced methods of measurement with the sizes of light sources taken into account. Later in 2001, IEC 60825-1 Amendment 2 provided for the division of laser into seven classes.
The laser used in CCS's ultraviolet LED lighting products corresponds to Class 3B. Never allow any direct or diffusely reflective ultraviolet beam radiate on the eye or skin. Directly looking into the light source may affect the health of the eye. Be sure to wear UV protective glasses when using the product and exercise caution in its handling. Regarding the device or equipment on which to mount the lighting, provide warning indication stating the use of ultraviolet lighting and ensure safety. See the "Ultraviolet LED Lighting Instruction Manual" for details. -
Caution
- Never directly look into or touch the ultraviolet beam.- Before turning the light on, be sure to put on UV protective glasses and prevent the light from entering the eye.- Do not turn the light on of the ultraviolet LED as the radiating (light emitting) section is directed at the human eye.- Wear long-sleeved clothes and gloves to prevent exposure of the skin for preventing the ultraviolet light from reaching the skin.- Be sure to inform all personnel involved in the use of the product or with access to the surrounding areas of the danger of ultraviolet LED. 
- The image taken may be affected by the emission spectrum distribution of the ultraviolet LED used and the spectral sensitivity characteristic of the CCD camera. For stable imaging, optimize the optical system including a CCD camera, lens and filter.
- For optimum imaging with ultraviolet lighting, use a CCD camera that is sensitive in the near-ultraviolet region. Ordinary CCD cameras are not very sensitive in the near-ultraviolet region, which may cause images to be darker or susceptible to disturbance light. Use of ultraviolet transmitting filters or ultraviolet cutting filters reduces the light intensity. Allow sufficient margins in the imaging conditions (lighting control, f-stop number, distance between the work and camera, distance between the work and lighting, etc.) when using such filters.
