Blocking light outside of the desired 1550nm range using a Bi1550 filter can be beneficial and can also help improve power efficiency and greatly reduce noise
The SP585 is useful for viewing hot rolled steel to see specific temperature areas while not blinding the system
The Bi632 blocks almost all interference from other red light sources
The ND090 has identical male and female threads on either end so it can be stacked with other ND filters to achieve various optical densities
Filters included in the NS100 have a surface quality of 60/40
Near-Infrared (IR) / Deep Red Absorptive Block Shortpass Filter, 370-630nm - MidOpt SP705 Size:30.5mm Blocking light outside of theThe MidOpt SP705 Near Infrared (IR) Deep Red Absorptive Block Shortpass Filter is an absorptive IR rejection filter recommended for blocking stray or scattered light from higher power near IR (NIR) light sources, particularly lasers, and protecting a cameras sensor. MidOpt Shortpass Filters have a broad, Gaussian passband to mimic and accommodate the entire output of the most common LED wavelengths, are anti reflection (AR) coated to limit glare and
