HummingBird 200pxOtO Photonics' HummingBird (HB) series are folded-cavity Czerny-Turner spectrometers offering the performance benefits of classic C-T cavity designs in a significantly more compact package. 

 

Despite its compact form-factor HummingBird sacrifices none of the performance of OtO's SmartEngine spectrometers - the optical bench provides excellent rigidity, ensuring a platform with industry-leading thermal, humidity, shock and vibration stability along with high optical resolution, high sensitivity, low stray light, and fast response.

 

Hummingbird is offered with a choice of three high performance 2048-pixel sensors in three package formats - "standard" (HB-2xx0), "External Motherboard" (HB-2xx4) and "No-SMA-905" (HB2xx4L).

OtO have designed HummingBird to offer the same configurability of grating and slit as their SmartEngine spectrometers enabling optimisation of spectral bandwidth, resolution and sensitivity. OtO's 5 standard operating ranges for HummingBird are:-

VNIRD 500 560nm 350-1020nm 1.0 1.4 2.1 4.4 8.4 12
NIR1 1200 850nm 790-1010nm 0.4 0.6 0.9 1.7 3.4 ~
NIR4 1000 900nm 790-1090nm 0.6 0.7 1.1 1.9 4.0 6.5

 

In addition to these standard operating ranges customers can specify their own operating "bandwidth" within the "Factory Selectable Band" specified in the table below. For example, the standard 1200/850 grating has a 220nm bandwidth which can be factory set within a 180-1010nm range, i.e. 180-400nm, 300-550nm, 790-1010nm etc. For each grating we show the achievable Resolution over the stated Spectral Bandwidth - thus enabling the combination of Grating and Slit to be identified.
