Detector-range for monochromators:
Choosing the right detector could be the most important decision when specifying a spectroradiometer.
From the experience gained in producing hundreds of spectral measurement systems, we have assembled a range of detectors to cover most applications.
Each detector is properly housed, complete with any associated circuitry and can be mounted directly at the exit slit of any of our monochromators.
The detectors below represent our standard range, but we also have working knowledge of many others, so please consult us if you do not find the detector you want.
 
 
 
Filter Based Detectors
We also offer a range of filter based detectors offering “close match” spectral responses to the desired function. For example, the DH400-VL photometric detector provides high accuracy illuminance and luminance measurements.
Some of the most common detector types are listed below:

The ORM400 Optical Radiation Meter is ideally suited to display the measurements from the DH400 range of detectors as well as third party current generating detectors. The ORM400 has a USB 2.0 interface and is supplied with powerful calibration features and data display functions. It includes a library of standard spectral light sources to which customers may add. This accommodates greatest accuracy and flexibility when measuring light sources with a filter based instrument.
