The miniature single-channel lens spectrometer S41 is developed on the basis of three-lens achromat–anastigmats used as collimator and camera objectives. This feature provides for a number of significant differences of the S41 from other spectrometers of its class:
• Miniature design
• High aperture ratio
• High linearity and wide dynamic range
• No need for an external power source
• Choice of spectral ranges and resolutions tailored to your requirementЙ
• The S41 is a very compact spectrometer
• Compared to reflective optics, lens objectives ensure lower stray light
• Objectives are centered systems providing calculation and correction of aberrations
As a result of the above mentioned advantages, the S41 features low stray light and no astigmatism in the image plane, thus ensuring high S/N ratio and good overall system sensitivity at using a height-limited linear image sensor.
The S41 comprises a built-in detector based on the Hamamatsu S8378-512 image sensor with the active area size of 12.8mm. The detector ensures excellent linearity, wide dynamic range and no modulation of broadband spectra.
