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:
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 REQUIREMENT
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.
Optical scheme of S41
The S41 spectrometer is convenient and easy to use: it is calibrated by the manufacturer, does not contain any movable parts, is controlled and powered from the computer via the Full-Speed USB interface.
The S41 can be triggered from your light source with standard TTL trigger pulses via the BNC-58 connector. The S41 is able to produce TTL trigger pulses as well.
The S41 delivery set contains a USB control cable, direct and reverse synchronisation cables and UV optical fiber. Light input with the optical fiber provides flexible arrangement of your instrumentation system. The S41 is able to operate without the optical fiber, with analysed light steered directly to its entrance slit.
The S41 spectrometer advantageous features listed above make it a popular device for spectrophotometric applications, along with research applications where precise quantitative analysis in the broad spectral range is required:
Spectrometric & spectrophotometric research
Industrial color measurements
Spectral evaluation of light sources, etc.
