CDS 1100 and CDS 2100



The base design of the CDS 1100 and 2100 is the proven Crossed Czerny-Turner spectrograph, with a top of the line electrically cooled back thinned illuminated CCD detector designed for highly efficient stray-light rejection. These spectral engines include user activated integrated shutters for real-time dark correction and the most intuitive software modules for research, development and production.

Labsphere's CDS 1100 and 2100 CCD array spectrometers are multi-channel spectral analyzers designed for real-time spectral characterization. When calibrated for the application with auxiliary hardware and LightMtrX software®, the instantaneous acquisition can provide the gamut of spectroradiometric photopic, colorimetric, electrical and thermal characteristics of the device under test (DUT).

The integral design and graphical user interface allow the spectrometers to easily transition from research to production.

LightMtrX Software® Platform with MtrX-SPEC Spectral Measurement Application Module

Sold separately, the LightMtrX, MtrX-SPEC software® is a comprehensive light test application package. It includes several modules allowing for data collection and system control of a variety of system configurations and applications. As expansion hardware is added to the core system, applicable modules become activated via a key code provided by Labsphere. Documented key codes enable Labsphere to easily track customer software releases in the field and allow for easy access to software revisions and upgrades. Purchase of the LightMtrX Service Package will allow LightMtrX users to automatically receive LightMtrX revisions and be notified when upgrades are available.
