OtO Photonics' Merak (MR) series are fully transmissive Czerny-Turner spectrometers offering ultra-high resolution of 0.04nm FWHM with a standard spectral range of 830nm to 970nm with best-in-class resolution of <0.1nm FWHM.
Merak is offered with a high speed 4096-pixel CMOS sensor providing high sensitivity and high resolution with continuous high speed exposure.
The standard spectral range of 830nm to 970nm makes Merak ideally-suited to applications such as laser diode and VCSEL measurement as well as 3D sensing, Laser Induced Breakdown Spectroscopy (LIBS) and other high resolution applications.
OtO have developed a new transmission Czerny-Turner optical cavity design for Merak featuring and patented adjustment mechanism allowing for custom wavelength ranges within the 180nm to 1100nm range, making Merak the ideal platform for high resolution measurement.
OtO's proprietary stray light calibration algorithm results in extremely low stray light (0.01%) and th
