Highest SNR PDA Miniature Spectrometer
VS70-PDA OEM Photodiode Array Spectrometer is a high performance compact fiber coupled spectrometer covering wide spectral range of 200 to 1000 nm. This VS70 system for industrial applications uses a modified VS70 optical engine with Horiba’s type-IV Aberration-Corrected Flat-Field Holographic Ion-Etched concave grating optimized for UV-VIS and a linear photodiode array.
This system is fitted with a custom multi-area order-sorting filter to eliminate higher orders and features a single-optics design for superior imaging, high sensitivity, high resolution and low stray light performance for bright-light applications such as emission, absorbance and reflectance.
For OEM Industrial Applications
Ideal for industrial bright-light applications such as emission, absorbance, and reflectance
Examples:
ㆍPharmaceuticals & life science
