UV Bandpass Filters

The BP250 filter is a broadband UV filter designed for deep-UV imaging applications and is available in a limited number of sizes.

To take advantage of this filter, high-end cameras or viewers with deep-UV sensitivity together with UV-optimised objective lenses are required.

This filter has peak transmission of approximately 40% around 235nm, gradually reducing to less than 0.3% at 405nm.

The BP250 is constructed using two specially coated pieces of glass cemented together with protected internal coating surfaces.

BP324 single substrate filters provide broad ultraviolet spectral bandwidth while effectively blocking visible and infrared light.

These filters are ideal for true UV imaging applications where suppression of longer wavelengths is essential.

Both the UV-A and UV-B portions of the ultraviolet spectrum are passed, while UV-C wavelengths are blocked.

Mounted and unmounted configurations are available for use with UV LED illumination systems.

The BP365 UV Blacklite dichroic filter is well suited for UV LED, UV fluorescent and other UV-producing lighting systems.

Designed to block visible light while passing UV wavelengths, the filter also supports 395nm wavelength LED illumination.

Constructed from low-expansion glass similar to Pyrex, the BP365 provides higher transmission than typically expected for UV bandpass filters.

Mounted and unmounted versions are available in sizes ranging from a few millimetres to over 600mm in diameter.
