Description
The SP445 shortpass filter transmits visible and part of the UV light below 445 nm and blocks wavelengths above. Within its working range it passes short waves and isolates long waves. Key features: wide blocking band for effective long-wave isolation; deep blocking that protects the short-wave passband; very steep transition with a narrow transition zone; and transmission above 90% in the short-wave region for efficient light use.
