Laser emission safety regulations are put in place to necessitate simple instrumentation for user monitoring and regulatory purposes. Instruments must be accurately calibrated and maintain their calibrations over long periods and must be achieved within the optical transducer. This white paper’s objective is to examine the suitability of silicon photodiodes as the transducer and to discuss the calibration accuracy, reproducibility, and stability that are likely to be achieved from a commercial company.
Ophir’s IS1.5-VIS-FPD-800 multifunctional sensor for measuring VCSELs includes precision photodiodes for calibrated average power measurements, fast measurements for pulse shape characterization on an oscilloscope, and an SMA fiber optic adapter for easy connection to a spectrometer.
Considerations when specifying transition pass bands, blocking bands, and transition widths include filter manufacturing tolerances, thermal tolerances, and source and detector variations, among others.
Hoya’s neutral density filters have nearly even spectral transmittance in the visible region and are classified by the average transmittance within wavelengths from 400 nm through 700 nm. These filters are able to control light intensity without selectively absorbing light with a specific wavelength.

Part 2 of the series describing advancements in CMOS sensors and processing focuses on a new Super 35 mm CMOS image sensor that is specifically developed to support origination of high dynamic range (HDR) motion imagery.
Trusting measurements from instruments can be difficult without a clear understanding of how the sensitivity and accuracy is derived. Many times, infrared camera measurement accuracy is confusing and can involve complex terms and jargon that may be misleading.
Alluxa offers a variety of hard-coated ULTRA Series excitation filters and emission filters specified with tight wavelength control, steep edges, high transmission, and greater than OD6 blocking to increase signal-to-noise ratios and improve qPCR efficiency. Available dichroic filters are specified with steep edges, high transmission, and high reflection.
