RBOtO Photonics' SilverBullet (SB) series are a new generation of ultra-compact Czerny-Turner cavity spectrometers featuring a single concave mirror in place of separate collimator and focussing mirror components.

 

This innovative arrangement provides the sensitivity and resolution benefits of a Czerny-Turner cavity design in an extremely compact form-factor with an overall size (including connectors and control boards) of only 40mm x 36.3mm x 25.1mm (~36cm³ ).

 

Despite its compact form-factor SilverBullet features an extremely rigid optical bench ensuring a platform with excellent thermal, humidity, shock and vibration stability.

 

The high speed 1024-pixel CMOS sensor and 8-bit 8051 microcontrollers provide high optical resolution and sensitivity along with short integration time, fast readout speed, high accuracy trigger timing and low power consumption.

Over time we expect additional grating and slit width options to become available with application-specific spectral range, sensitivity and resolution characteristics. Please feel free to discuss your application's needs to see if we can match to existing configurations or develop an optimised solution.

Power and communication with SB-Series spectrometers is via high speed micro-USB with the addition of 6 user-programmable digital I/Os.

 

The inclusion of OtO's SpectraSmart software ensures that SilverBullet users can be up-and-running within minutes whilst the availability of a Software Development Kit for Windows and example code for Linux facilitates integration into a broad range of OEM instruments.
