Andover Corporation 228nm Optical Bandpass Filter, HBW 25nm, 25mm dia.

Optical bandpass filters are designed to transmit a well-defined band of energy in the electromagnetic spectrum. Andover offers one of the most extensive listings of standard "off-the-shelf" optical filters in this industry. Wavelengths range from 193nm in the ultraviolet through the near-infrared and include many of the primary laser, mercury, biomedical and analytical spectral lines. All UV filter glass is overcoated with a hard oxide protective layer to prevent degradation in harsh environments. Standard sizes include 12.5mm Ø, 25.0mm Ø, and 50.0mm Ø. All Andover optical filters are mounted in black anodized metal rings which provide an added measure of protection against chipping, scratching, and high humidity conditions. In addition, all-optical filters have their part number permanently engraved on their edge and each filter is supplied with a calibrated spectral bandpass data curve at no charge. Custom spectral data is available and will be quoted upon request. Custom shapes and sizes are readily available.
