Monochromators and Spectrographs

monochromator separates incoming light into its component wavelengths, selecting only a very narrow bandwidth of interest to output. Spectrograph separates incoming light into its component wavelengths for recording and analysis.

The Sciencetech 9030 monochromator is a compact, single grating scanning monochromator. It has a manual wavelength selector dial with an optional external motor drive for computerized control. The compact design is made possible by its Seya-Namioka optical layout, using a single holographic concave grating and f/3.2 aperture. A pair of removable fixed-width slits are included for the input and output ports. Additional removable slits and custom width slits can also be purchased separately.
Mirror coatings have been chosen for this model to enhance performance in the VIS-NIR region.
There are 5 grating choices (sold separately) covering from UV to near-IR; choose a VIS to NIR range to pair with the VIS-NIR mirror coatings on this model. The 9030 monochromator cannot be used as a spectrograph and therefore only accepts single channel and PMT detectors; however, it can be used as an excitation wavelength tunable light source.
The 9030 is Sciencetech's most economical monochromator with a manual control wavelength selector and removable, fixed-width slits. The input and output ports are purposely placed optically in-line, making it a simple addition to a straight line beam in an optical system. Being a scanning monochromator, it does not have a flat output field and hence cannot be operated as a spectrograph with a multi-channel detector mounted at the output port.

An imaging 1/4m Monochromator/spectrograph. It has f/3.5 aperture and a 2D flat field output for multi-channel use. It has a nominal resolution of 0.15 nm.
Special toroidal mirror makes additional astigmatism correction. This spectrograph provides superior image quality over area 25 mm wide and 12 mm high
The unique layout with mirrors of unequal input and output (200mm and 250 mm) focal length is optimized for minimum coma while allowing high throughput and minimum stray light and vignetting
Please contact a technical sales member to discuss coupling options.
For more information, please see the technical datasheet.

The 9057 is a half meter monochromator and spectrograph with an f/8 aperture. This system is a Czerny-Turner design optimized to reduce aberrations.
This monochromator supports up to three 50x50mm gratings on a computer controlled turret. It includes a single input slit by default; please select appropriate output mounting (slit, detector or CCD mounting, etc...) when ordering.
A fast version of the 9057, the 9057F, operates with 64x64mm gratings and offers better throughput with the same optical pathlength. Please discuss with your Sciencetech technical sales staff member to find if the 9057F is a better choice for your particular application.
