Optical Spectrometer Features
Dynamic Spectral Range
Capable of meauring the entire visible light spectrum, from the UV-A band to near infrared. With a range of 320 nm to 1050 nm and resolution of up to 2.5 nm, our system can be used to study a wide range of materials including photovoltaic, solar cell, OLED, biological, and 2D materials.
Fast Acquisition Speeds
A powerful Arm Cortex M4 processor works with a high-speed 16-bit, 500 kSPS, analog-to-digital converter. Our system can transfer over 100 frames-per-second to the host computer when running in internal trigger mode. Plus, a six port I/O expansion header allows for easy integration with other 5V equipment.
Compact and Modular Design
The clever design of the Ossila Optical Spectrometer combines optical elements and internal electronics into an extremely small footprint. The result is a lightweight, compact but powerful UV-Vis-NIR spectrometer.
Internal and External Trigger Modes
Use in free-running mode, or integrate with other systems using the external trigger input. The rolling integration mode lets you control the integration time dynamically. With an output to synchronise acquisition with an external shutter plus two general purpose outputs, it features six I/O ports in total, including a ground port.
USB Powered
Power your optical spectrometer via the USB port. There is no need for an additional, dedicated power supply. Get up and running quickly and easily with either your computer or laptop - simply plug in via the USB port and begin measuring.
Testimonials
I have been using the Ossila Optical Spectrometer in my research to measure absorption, transmission, and reflectivity. I highly recommend it to anyone who is looking for a cheap, fast, reliable and easy-to-use spectrometer for their optical experiments.
