Photolithographic and astronomic filters are available in this section. The different optical filters available are as versatile as the applications are varied.
Interference filters with a full width half maximum of 8 nm and 3 nm as well as an optical density of OD5 at a transmission of >90%.
Our partner, Omega Optical, has developed a series of interference filters for clinical chemistry and biomedicine. The two basic versions feature an excellent signal-to-noise ratio at competitive prices.
8 nm Full Width at Half Maximum with OD5
The first type of interference filters, which has a full width at half maximum of 8 nm, was developed according to the industry standard. With a suppression rate of 1:100,000, the blocking of this filter is superior to conventional filters.
3 nm Bandpass with OD5 Blocking
The second type has a full width at half maximum of 3 nm, which leads to a higher degree of selectivity and delivers more precise measurement results. The suppression rate of the blocked wavelengths is 1:100,000.
These filters are available in standard ring diameters of 10 mm, 12.7 mm, and 15 mm as well as with an edge length of 6 mm as a quadratic version.
