Mini-Chrom Monochromator Accessories

Interchangeable Slit Sets

A 300 micron pair of slits are included with each Mini-Chrom. Additional slit sets can be purchased to optimize resolution or throughput. Slits are available in 50, 100, 150, 300, 600 and 1000 micron widths, all 4 mm in height.

Changing the slit assemblies in any Mini-Chrom takes only a few seconds and no tools. The slit assembly consists of a precision slit photo etched in a black oxide coated brass disc, a slit spacer, slit cover and two banana plugs. The banana plugs allow the assembly to be easily inserted or removed while assuring alignment of the slit with the monochromator.

Note: Slits should always be changed in pairs.

Aperture Adapters

The Aperture Adapter converts the entrance and/or exit slit ports to accept SMA 905 compatible optical fiber assemblies.

Holmium Oxide Calibration Filter

Comprised of 2.5 mm thick holmium oxide filter glass mounted in a metal holder. A spectral scan showing calibration wavelengths from 350 nm to 800 nm is included. A comparison between the reference scan and the indicated wavelength takes only a few seconds.

Higher Order Blocking Filters

Required to block higher order (λ/2, λ/3, λ/4, etc.) radiation. Higher order blocking filters are Optometrics’ Long Pass Cut-On filters mounted in a ring./product-category/optical-filters/longpass-filters/

Blocking filters need to be matched to your specific monochromator. For assistance choosing the correct filter, please contact us to order the correct model for your Mini-Chrom Monochromator and application.
