As with calibrations of spectrophotometers, optek's new series of calibration filters test:

1. Photometric Accuracy and Linearity – absorbance up to 2.4 now available.

2. Stray Radiant Energy / Blocking – most important test for any photometric measure.

3. Wavelength Verification and Spectral Stability – ensures consistency of measurement.

New design architecture effectively eliminates measurement offsets due to inter-reflections.

And now:

4. Optek's new and unique Calibration Cuvette FH03 allows non-intrusive introduction of product samples or liquid calibration standards for direct comparison to your laboratory spectrophotometer.

--------------------------------------------------------------------------------------------------------------------------------------

The unique Calibration Cuvette enables product calibration without the need to interfere with the process line. It allows you to create a correlation of absorption signals to the concentration of product or an equivalent substance, creating an easy link from lab to process.

Three new solid filter series are now available to ensure confidence in your measurements. The UV-L filter series is used to calibrate photometric accuracy and linearity. The UV-B filter series verifies integral blocking and the UV-S filter series tests for long term stability of the sensor.

All optek filters ship with NIST-traceable certification. Optek is equipped with an extremely high quality NISTtraceable calibrated spectrophotometer assuring quality and quick turn around time for recertification of filters.
