Calibration Filter Sets

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 the verification of transmittance and 1 clear holder for use as a balancing filter. The transmission value of each filter is certified by measuring it on a spectrophotometer that has been calibrated with standards that are directly traceable to the NIST.

Each filter is mounted in a black anodized aluminum holder, which is compatable with the 1cm cuvette holder, that is supplied with most spectrophotometers. Individual filters are suppled with removeable shutters to protect the filter glass from damage.

Every filter set is shipped with a Certificate of Calibration stating the transmission value of each filter at five different wavelengths (440nm, 465nm, 546.1nm, 590nm & 635nm). The transmission accuracy of each filter is certified to be within ±1%.

All filter sets are shipped in black anodized metal cannisters which provides maximum protection during shipment and storage.

If you already own a Calbration FIlter Set, and need it recertified, please contact our sales department to arrange a return.
