VS70-PDA

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:

Pharmaceuticals & life science
Semiconductor
Liquid chromatography
Environment, agriculture and energy
