With the fastest direct drive in this class, FHR 640 and FHR 1000 spectrometers offer a unique combination of speed, precision and high resolution, completely revolutionizing the large spectrometer market. Designed for researchers who require high accuracy with immediate results, the versatility of the FHR allows for utilization over a wide spectral range, extending from the UV to the IR. The instrument’s cast body design eliminates temperature induced stress and expansion, preventing any significant wavelength shifts or signal loss and allowing for optimal performance. These monochromators also benefit from the highest quality of gratings, also designed and manufactured by HORIBA.
The FHR640 and FHR1000 are automated Czerny-Turner spectrometers, featuring a 0.64 m focal length (FHR640) and a 1 m focal length (FHR1000). Especially designed for researchers who require high accuracy with immediate results, the versatility of the FHR series allows for utilization over a wide spectral range, extending from the UV range (140 nm) to the IR (depending on the grating and detector used).
The FHR has been designed to minimize any stray light reaching the focal plane. The optical cavity includes blackened baffles and masks to trap unwanted light. In addition, the optical design of the FHR is free from re-diffracted light (re-diffracted light is a source of stray light that involves multiple reflections off the optical components themselves and is therefore very difficult to mask).
The FHR Series has automated motorized entrance and exit slits. In the standard version, each slit may be set between 0–2 mm, and there are optional slits which may be set between 0–2 mm. The slits are internal to the monochromator. A manually adjustable height limiter allows the user to quickly shut or open the light path and also set to a 1 mm height.
You can add accessories to the FHR Series spectrometers to obtain optimum results for a variety of applications. To attach the accessories to the FHR, use the two tapped holes on the body of the height limiter on the outside of the monochromator (shown below). These holes are also useful for connecting the FHR with your experiments and equipment. When connecting with the FHR, it is important to know the distance from the mounting face of the slit’s body to the slits.
Note that some custom accessories require removal of the height-limiter assembly in order to be attached to the FHR chassis. To remove the height-limiter assembly, remove the four screws holding the assembly onto the chassis.
Since the acquisition by HORIBA of Jobin Yvon, a spectroscopy company founded in 1819, HORIBA Scientific has continued to define the leading edge of the Optics of Spectroscopy.
For the last 40 years HORIBA Scientific has taken a leading position in the design, development and manufacture of master and replica diffraction gratings. HORIBA Scientific diffraction gratings are found in both high volume OEM instruments and in world class cutting edge scientific applications. Our pattern of leadership in optics has been hallmarked by the continuing development of both classically ruled and holographic diffraction grating technologies. This led to the introduction in 1967 of the aberration corrected holographic grating and subsequently ion etched and blazed concave and plane holographic gratings.
The FHR series of spectrometers take full advantage of the highest quality of gratings that HORIBA designs and manufactures..
There is a wide selection of gratings to choose from depending on optical requirements. Gratings are 50 x 50 mm for the FHR. There are three different types of gratings available; classically ruled, holographic, and blazed holographic. There is also a flat mirror that may be ordered for the dual grating turret option.
Ruled gratings | Select for applications where high throughput or low groove density is required, or when working in the infrared. Typically, they have high throughput at the cost of higher stray light. |
|---|---|
Holographic gratings | Available in higher groove densities for finer resolution requirements and are excellent choices for experiments with laser excitation such as Raman or laser induced photoluminescence. They provide the lowest possible stray light possible, sometimes at the cost of lower throughput. |
Blazed holographic gratings | These gratings have the same advantages as holographic gratings with better throughput. |
Ruled gratings and blazed holographic gratings have two fundamental parameters to choose from; the groove density, expressed in grooves (or lines) per millimeter, and the blaze angle which nominally refers to the peak reflectance wavelength expressed in nanometers.
The groove density of the selected grating affects the resolution and mechanical scanning range of the monochromator. Below is a reference chart showing the affect groove density has on the mechanical scanning range of the monochromator as well as the reciprocal linear dispersion of the slits.
Groove Density (gr/mm) | Typical Linear Dispersion (nm/mm) | Mechanical Scan Range (nm) |
|---|---|---|
