The model S41 miniature lens spectrometer is using a three lens achromat-anastigmat as collimating and camera optics. The input is fiber-coupled, the system exhibits high linearity and wide dynamic range. Spectral ranges from UV to IR are covered by three models. The S41 is computer-controlled via USB and does not require an external power supply.

The compact spectrometer S100 covers an extremely wide spectral range with only one grating, with a resolution of 1 nm from 190-1100 nm. The device is easy to use, as it operates from USB, does not require an external power supply, is calibrated by manufacturer and has no movable components. The input is fiber-coupled, three CCD detectors are available for different requirements. The software included is user-friendly and provides a wide range of measurement options.

The compact spectrometers of series S150 provide a wide range of gratings and detectors to meet the specific user requirements and allow matched selection of spectral range and resolution. S150-II versions have two built-in gratings, which can be easily selected by a shutter. All devices are fiber-coupled, operate by USB without external power supply and come with user-friendly software.

High-aperture spectrometers of SDH series offer a variety of options both regarding the choice of gratings for best spectral range and resolution down to 0.06 nm, as well as different Si- and GaAs-detectors for ranges from 200 nm up to more than 2.5 µm. Variants with one as well as 4-grating turret are available. All models are fiber coupled and equipped with a multi-position input filter for spectral order cutting. Control and powering is through USB with a user-friendly software.

The SHR is an Echelle spectrometer with outstanding precision of +/-3 pm, having a resolution power of 1:30000 within 190-1100 nm. It is the ideal high-precision instrument for measuring laser wavelengths and linewidths. The SHR is fiber-coupled and delivered with an input attenuator for easy use. The instrument does not contain any movable parts, operates and is powered from USB and comes with a user-friendly software for measurement and online monitoring.

The M266 is a compact versatile instrument with high aperture and low stray light and can be used as monochromator as well as flat field spectrograph. M266i versions with additional optics and astigmatism-compensation moreover have imaging quality and can be used with 2D-array detectors. A wide range of options for the input and 2 output ports, fully automated control of filters and up to 4-grating turrets as well as a wide range of available detectors together with the versatile software provide wide possibilities in processing and analysis.

The infrared spectrometer ASP-IRH covers a wide spectral range from 1220 nm up to 2580 nm. It is equipped with a InGaAs pin photodiode as detector and fixed input slit and reaches a high resolution power using either the free space or fiber input. It is the ideal device for the laser wavelength monitoring and spectral analysis of IR light sources.
