OtO Photonics' SmartEngine (SE) series are compact Czerny-Turner cavity spectrometers available in a wide range of configurations to meet the demands of many applications.
SmartEngine's optical bench is compact and rigid, providing a stable platform enabling excellent thermal, shock and vibration performance with high optical resolution and sensitivity, low stray light, and fast response.
A choice of high performance CCD and CMOS sensors from leading manufacturers (Sony, Hamamatsu, Toshiba) are available, offering optimisations for characteristics such as deep-UV, UV or NIR-enhanced response; high sensitivity, dynamic range, SNR; high speed or high pixel count.
There are also three high performance processor platforms, developed in response to customer demand and to incorporate new technologies as they become available.

~80% of range Suitable for most applications |
| SE3xxx SE4xxx |
FX2LP | 8051 16-bit/48MHz |
Low power consumption |
| SE5xxx SE6xxx |
S7G2 | Cortex M4 250MHz |
Double height chassis Combines attributes of Z5 and FX 100Mb Ethernet (Gb in development) |
A detailed description of each platform, including features such as flash and RAM, UART communication, frame buffer, triggering etc., is available in the Support: Spectrometers links.
The key to SmartEngine's flexibility is the wide choice of sensor, slit size and grating designs which can be mixed-and matched to create a huge range of application-optimised spectrometers. To help new users the Support section of our site contains guidance on How To Specify A SmartEngine. You can also find recommendations for specific applications in the SmartEngine By Application page.

SmartEngine spectrometers can be specified with OtO's "PKG" Spectral Measurement Kit, a multi-function measurement solution designed to accommodate one or two SmartEngine spectrometers and a choice of light source. The rigid optical bench is machined to ensure easy alignment of spectrometer(s), light source and cuvette holder ensuring quick-and-easy setup and operation. A selection of colour (RGB) and Neutral Density filters are included, along with freespace and fibre collimators, adapters, and cuvettes - all housed in a rugged, waterproof storage and carrying case.
The inclusion of OtO's SpectraSmart software ensures that the PKG Spectral Measurement Kit is an ideal solution for teaching environments as well as a broad range of industrial, medical, pharmaceutical and environmental applications.
