Rectangular Optical Filters Datasheets

435.8nm CWL, 40.0nm Bandwidth, 120.0 x 20.0mm dia. Optical Bandpass Filter -- 435.8 / 40.0 - 48749
from Andover Corporation

Andover maintains a stock of high-quality surplus optical bandpass filters. These are primarily overruns of custom production lots, and exhibit the same high level of quality as all of our other products. Consequently, this can be a very economical alternative to purchasing a custom bandpass filter. [See More]

Contrast Enhancement Filters
from SCHOTT AG

Contrast enhancement filters allow only certain wavelengths of light from a display device to pass through and filter out irrelevant wavelengths. The displays are thus able to achieve a higher level of contrast. Furthermore, full color displays are capable of reproducing colors more naturally. The... [See More]
