HOLMARC’s New 125mm & 150mm focal length CT monochromators are compact mini optical system delivering a high performance, reliable solution wide scan wavelength measurement over UV-VIS-IR region (185nm - 3300nm). Its features are comparable to many larger, more expensive, conventional models. At just 16 x 8cm the 125F5 monochromator (20 x 10cm for 150mm F6 monochromator) features a compact design with a single entrance and exit slit with up to two diffraction gratings ideal for accommodation into the smallest of spaces available, particularly suitable in OEM applications.

The 150F6 monochromator is ideally suited to measurements whereby a medium to lower spectral resolution is required, i.e. as tuneable light source, wavelength scan measurement system etc. Suitable for integration into a larger measurement system. Because of the compact design it can be used in a variety of sophisticated analytical and biomedical equipment such as: clinical chemistry analyzers, HPLC detectors, and UV-VIS-NIR spectrophotometers.

Manual Mini Monochromator

125 mm F5 & 100 mm F4 - Handheld Size


HO-SP-125F5 & HO-SP-100F4 Series


HOLMARC’s MMS-125F5 hand held Mini Monochromator is a manually operated light weight monochromator size of that utilizes a knob dial and a precision linear engraved top for wavelength selection. For quick wavelength selection a quick release lever also provided. Precision lead screw sine bar mechanism is used for the rotation of the diffraction grating which positions the selected wavelength at the exit slit. Wavelength can be read directly in nanometers from engraved top.

These are ideal choice for compact wavelength selection system. 0-5 mm micrometer controlled variable slit is used for the wavelength band width controls. Narrower slits increase resolution but decrease throughput. Wider slits increase throughput at the expense of spectral purity.

# Note: It is possible to converts slit aperture to SMA connector.
