Raman and Resonance Raman Spectroscopy of Enzymes
The TRIAX and iHR series spectrometers used in Raman system configurations provide superior imaging performance with no re-diffracted light and maximized optical throughput.
iHR Series
Mid-Focal Length Imaging Spectrometers
The iHR Series of 320 mm and 550 mm focal length high performance and versatile imaging spectrometers are HORIBA’s most popular and iconic spectrometers. The iHR series is built on decades of experience in spectroscopy and represents the highest quality, performance and versatility of any spectrometers in this class. The iHR 320 and iHR 550 spectrometers are immediately recognizable around the world by their unique shape, the result of a superior optical design. These spectrometers benefit from the highest quality of gratings, also designed and manufactured by HORIBA. The iHR series is ideal for applications such as:
- Raman
- Fluorescence
- Photoluminescecne
- Absorbance / Transmission / Reflectance / Emission Analysis

Gratings
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. Please click on the link below to view all our grating options.
Computer Control
In addition to wavelength control the Triax Series has an optional automated turret control and automated control of the optional internal five position filter wheel. There are multiple software platforms to choose from for spectrometer control and acquisition. Please click on the link below to view all our software choices.

Photoluminescence of InGaAs/GaAs Quantum Dots
InGaAs/GaAs and InAs/GaAs quantum dots (QDs) have been identified as suitable candidates for various applications in the terahertz range by using their intraband carrier transitions.
Photoluminescence and Photoreflectance
As a result of rapid development in semiconductor manufacturing, many types of optoelectronic
devices such as laser diodes, LEDs, and high-electron-mobility transistors (HEMTs) are now fabricated by epitaxial-growth methods.
Evaluation of Novel Photoresponsive Materials via EQE Measurements
Internal Quantum Efficiency (IQE) and External Quantum Efficiency (EQE) measurements are indicators of the effectiveness of a photosensitive device such as those used in telecommunications and solar cells. EQE is the ratio of the charges generated to the total amount of photons incident on the surface; a larger EQE indicates a more efficient device.
Characterization of Semiconductors with Photoluminescence Measurement System
Photoluminescence is the optical emission obtained by photon excitation (usually a laser) and is commonly observed with III-V semiconductor materials. This type of analysis allows non-destructive characterization of semiconductors (material composition, qualitative investigations, etc.
