Metallic neutral filters
Description
These filters consist of a thin layer of nickel-chromium alloy vacuum-deposited on a glass substrate. This gives excellent neutrality and very accurate attenuation. About half the rejected light is absorbed and the remainder reflected, so these filters can also be used as beamsplitters.
Our Visible/IR range have low-expansion borosilicate glass substrates and cover the range 350-2500nm.
Our UV range are on a synthetic fused silica substrate and extend the useful range down to about 170nm. Note that the density of all filters is specified at 550nm, but in the UV it can be up to 40% higher - see graphs.
- Mounting (25mm dia. only)
- All filters can be cut down or edged to special sizes
- Mounting in camera filter rings (See camera filter holders)
