Bessell Photometric Filter Sets
Our stock Bessell
Photometric Sets manufactured to the prescription put forth by M.
Bessell, offer high optical quality suitable for demanding imaging
requirements. Filters are polished to stringent transmitted wavefront
distortion, wedge, and flatness specifications and are then
anti-reflective coated. Each filter's spectral response is determined
by the combined response of two or three Schott filter glasses
polished to prescription thicknesses. The individual glasses are then
laminated into a single-piece optical assembly. The result is a set
of precision prescription filters at an economical price.
If your application
requirements differ in physical dimension or optical performance from
our stock items, we can customize individual filters or sets.
