Spectroscopy Solutions - Short Focal Length Triple Grating Imaging Spectrographs – Triax Series

Triax Series Imaging Spectrograph

Affordable 190 nm focal length imaging spectrometers offering maximum versatility and automation

Available as an imaging spectrograph or a scanning monochromator, HORIBA’s Triax triple grating spectrometer offers maximum versatility, automation, and affordability at a level of optical superiority that our users have come to expect from HORIBA. These spectrometers benefit from HORIBA’s patented and revolutionary triple grating turret assembly that has two independent axis of rotation , controlled by a single stepper motor, to control wavelength position and grating switching. To switch gratings the turret rotates about the center axis, but to scan wavelengths the turret rotates around the front face of the grating to maintain on axis rotation of the grating. These spectrometers also benefit from the highest quality of gratings, also designed and manufactured by HORIBA.

Two configurations to choose from

  • Manual Slits with single entrance/exit ports (Triax 180)
  • Automated slits with single entrance and single or dual exit ports (Triax 190)
Segment: Scientific
Division: Custom Spectroscopy Solutions
Base product
  • Low cost triple grating spectrometer
  • Patented grating turret design
  • Good image quality
  • Monochromator or imaging spectrograph
  • Optional second exit port (Triax 190 )
  • USB interface

Hardware

Slits

The Triax has the following slit types available

  • Automated 2 mm slit (part number MSL-TXB2)
  • Automated 7 mm slit  (part number MSL-TXB7)
  • Fixed entrance and side exit  (Triax 190 only, part number MSL-TNFA)
  • Fixed exit (part number MSL-TXF)

The Triax automated slits adjustable from 0 to 2 mm opening or 0 to 7 mm opening.  A manually adjustable height limiter allows the user to quickly shut or open the light path to 1 mm and 15 mm heights.

You can add accessories to the Triax-series spectrometers to obtain optimum results for a variety of applications. To attach the accessories to the Triax, use the two tapped holes on the body of the slit. These holes are also useful for connecting the Triax with your experiments and equipment. When connecting with the Triax, 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 Triax chassis. To remove the height-limiter assembly, remove the four screws holding the assembly onto the chassis.

Fixed Slit Assembly

The fixed slit assembly can hold different slit inserts ranging in physical size from 0.025 to 2 mm, and for the 1200 g/mm grating the reciprocal linear dispersion of the Triax is 3.53 nm/mm.

Gratings

World Class Diffraction Gratings Manufactured by HORIBA

A Proud Tradition of Excellence

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 Triax series of spectrometers take full advantage of the highest quality of gratings that HORIBA designs and manufactures.

A Vast Array of Choices

There is a wide selection of gratings to choose from depending on optical requirements.  Gratings are 32 x 32 mm for the MicroHR. 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.

Groove Density

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.

Unique Triple Grating Turret Assembly

These spectrometers benefit from HORIBA’s patented and revolutionary triple grating turret assembly that has two independent axis of rotation , controlled by a single stepper motor, to control wavelength position and grating switching. To switch gratings the turret rotates about the center axis, but to scan wavelengths the turret rotates around the front face of the grating to maintain on axis rotation of the grating.

Below is a comprehensive list of available gratings for the MicroHR series of spectrometers. Other gratings are also available upon request.
