The MicroHR is the ideal imaging monochromator for integration into optical systems.

With a focal length of 140 mm and a footprint smaller than a sheet of paper, the MicroHR provides a spectral resolution of 0.3 nm and can be configured with a manual or a motorized turret. By selecting the most suitable set of diffraction gratings and the right detector the MicroHR monochromator can acquire data from 180 nm to 20 microns.

The MicroHR monochromator can be configured with a second exit slits to fit an additional single or multichannel detector. This compact monochromator includes all the features of a high-end monochromator at a fraction of the cost.

The iHR 320 is a 320 mm focal length Czerny-Turner imaging monochromator.

The unique shape of the iHR320 scanning monochromators is the result of 190 years of experience in optical design. The iHR320 monochromator uses toroidal mirrors to bring the center of the tangential and sagital focal planes together. This design has the advantages of providing imaging capability when using a CCD detector while optimizing spatial resolution at the edge of the multichannel detector.

The iHR320 monochromator is the first monochromator on the market that can be configured with two entrance and two exit ports for maximum measurements flexibility.

This monochromator provides the best image quality, remove the re-diffracted light and maximize the optical throughput by using a F/4.1 aperture.

Don’t underestimate the importance of a well designed and accurate monochromator for your experimental works. Choose the best instrument on the market and ask us about our iHR monochromator series.

If you need a high spectral resolution imaging monochromator, the iHR550 scanning monochromator is the best choice on the market.

With a focal length of 550 mm, a Czerny-Turner optical design and the use of toroidal mirrors, the iHR550 imaging monochromator offers a unique set of specifications.

Unlike multiple-plates made monochromators, the iHR series monochromators are made of a single cast. This eliminates light leak and decrease stray light level.

With a total of 3 gratings mounted on an automated turret and 4 external ports, the iHR550 is an highly flexible monochromator that will fulfill the most demanding spectroscopic and imaging experiments.

Combined with our large offering of single channel and multichannel detectors, the iHR550 monochromators will exceed the level of spectral resolution, accuracy and reliability required for your absorption, photoluminescence or Raman experiments.

Drop the H1034B OEM monochromator into your product, add a detector and / or light source and take data immediately. Each unit is pre-aligned at the factory, set-up with a stepper motor and tested in accordance with your requirements, ensuring consistently high performance. Holographic gratings, pioneered by HORIBA Jobin Yvon, deliver performance not possible with other small designs. Ion-Etched gratings combine the advantages of holographic gratings with a high efficiency. Aberration-corrected concave gratings permit a one-piece optical design with excellent imaging properties, a plus if you want to collect the output light into fiber optics.

A monochromator is an optical subassembly that accepts polychromatic input light from a lamp or laser and outputs monochromatic light. Typically, the entrance ports, which may be slits or optical fibers, are geometrically fixed. Internal to the device, the dispersive element, a diffraction grating, is rotated, either manually or by motor. The angle to which it is turned determines the wavelength of the output light. The result is a versatile, selectable, monochromatic source of light.
