Andover Corporation is a recognized world leader in the manufacture of high-quality optical filters and coatings. They manufacture a broad array of standard and custom components including bandpass, ND, long- and short-pass, heat-control filters, and more. Wavelengths from UV to Mid IR. Deposition techniques include ion-assisted e-beam deposition (IAD), and magnetron sputtering. Applications include machine vision, photolithography, water and gas analysis, calibration, etc.
IR Gas Analysis Filters now in stock at Andover Corporation
Andover Gas Analysis Filters isolate specific regions of the spectrum, simultaneously providing high transmission of desired energy, and deep rejection of unwanted energy. Constructed of hard, durable first-surface dielectric coatings on optical-quality IR-transmitting substrates, these filters will withstand normal cleaning and handling associated with any high-quality optical component. For your convenience and economy, Andover offer the filters in 25mm dia. However, we can produce custom sizes and shapes, as well as custom optical characteristics.
Spectrophotometric Standards - NIST-Traceable Calibration Filters AC-930 and AC-1930
These spectrophotometric glass standards are intended for use as secondary standards for the verification of the transmittance and absorbance scales of visible absorption spectrometers. Each set contains 3 glass filters for transmittance verification and 1 clear holder for use as a balancing filter. The transmission value of each filter is certified using a spectrophotometer that has been calibrated with standards that are directly traceable to NIST.
