PocketHawk-NIR is OtO Photonics' folded-cavity Czerny-Turner NIR spectrometer offering the performance benefits of classic C-T cavity designs in a significantly more compact package.
PocketHawk-NIR is dramatically smaller than OtO's SideWinder Czerny-Turner cavity NIR spectrometers at just 65 x 65 x 29.8mm³ (<126cm³) including the external control board and yet the optical bench provides excellent rigidity, ensuring a platform with industry-leading thermal, humidity, shock and vibration stability.
PocketHawk-NIR is offered with a choice two models:-
- PH2524, Hamamatsu G8160 128-pixel InGaAs linear sensor
- PH2534, Hamamatsu G9203 256-pixel InGaAs linear sensor
Both models cover a spectral range of 900nm to 1700nm - achieved using different gratings. Slit sizes of 50µm, 100µm and 200µm can be selected, providing FWHM resolutions shown below where "xxx" is the slit width:-
| Model Name |

| 50µm | 100µm | 200µm | |||||
| PH2524-xxx-NIRC1 | 150 | 1250nm | 800nm | 900-1700 | 10-16 | 18-22 | ~30 |
| PH2534-xxx-NIRC2 | 300 | 1200nm | 800nm | 900-1700 | 5-8 | 9-11 | ~15 |
The optical input is via an industry-standard SMA-905 multimode fibre connector whilst the externally mounted control board incorporates a 16 bit, 15MHz A/D converter with electrical interface via an external control board featuring a high speed (480Mbps) Micro USB 2.0 connector or 8-pin extension port.
OtO's SpectraSmart spectral management software is supplied with PocketHawk and includes a Windows Software Development Kit. Example code for control via Linux is also available upon request.
