Ultra-compact Czerny-Turner spectrometer showcasing at WWEM 2024

12 Aug, 2024

AP Technologies is pleased to announce they will be demonstrating OtO Photonics’ innovative ‘Bullet-series’ spectrometers on stand J6 at WWEM this October.

Bullet spectrometers bring the sensitivity and resolution advantages of the classic Czerny-Turner cavity design but replace the conventional arrangement of separate collimator and focussing mirror with a single complex concave reflector design.

The design of the Bullet series enables a significant reduction in the overall size of the spectrometer - as small as 36mm x 40mm x 25mm (~36cm³ ) including connectors and control board.

OtO are offering two versions of the Bullet design – ‘SilverBullet’ is based on a 1024-pixel CMOS sensor for 180nm to 1100nm performance whilst ‘RedBullet’ utilises a 128-pixel InGaAs sensor for 900-1700nm sensitivity.

All Bullet series spectrometers are based on 8051 microcontrollers which allow for short integration time, fast readout, highly accurate trigger timing and low power consumption. Power and control is via USB with the addition of six I/O pins for connecting external devices.

As with all of OtO’s spectrometers the Bullet series spectrometers are supplied with their SpectraSmart spectral measurement software and a full Windows SDK. Example code for other operating systems is also available.

SilverBullet is currently offered with a choice of 11 gratings giving operating widths of 170nm to 820nm  in 16 configurations with spectral ranges of 180-350nm up to 300-1100nm. A choice of 25µm, 50µm and 100µm slit width allows users to optimise sensitivity, with resolution from 1.7nm FWHM (180-350nm, 25µm slit) to <21.5nm (300-1100nm, 100µm).

RedBullet covers the range 900nm to 1700nm with a 50µm slit width giving resolution of <15nm FWHM across the full range.

To see the new Bullet series spectrometers visit AP Technologies on J6 at WWEM.
