X
& Y offers IR cut filters and optical low
path filters (OLPF) at competitive prices for
cell phones and digital camera applications. Absorption,
and particularly wavelength selective absorption,
is an important factor in the functioning of filters.
The two most common absorbers are thin metallic
films, which are particularly insensitive to wavelength
for absorption, and colored glasses, which absorb
wavelengths varying by as much as several orders
of magnitude in only tens of manometers. Interference
filters are multilayer dielectric thin film devices.
Metallic films, coloured glasses and thin dielectric
film filters are all available from X&Y provides
all kinds of filters including IR Cut Filter Interference
Filter, Colour Glass Bandpass filter, Neutral
Density Filter (Absorptive) Neutral Density Filter
(Reflective) etc. |
