HORIBA Jobin Yvon OEM Volume-Production Diffraction Gratings

Overview

HORIBA Jobin Yvon OEM Volume-Production Diffraction Gratings are precision optical components engineered for integration into commercial spectroscopic instrumentation—including monochromators, spectrometers, optical emission analyzers, and portable Raman or fluorescence systems. Leveraging over six decades of expertise in high-performance grating design and fabrication, these gratings apply advanced ion-beam etching and aberration-corrected holographic techniques to deliver reproducible spectral dispersion with high diffraction efficiency and low stray light—critical for quantitative analysis in regulated environments. Unlike research-grade gratings optimized for single-unit performance, this OEM series is manufactured under strict statistical process control (SPC) to ensure batch-to-batch consistency across thousands of units, enabling instrument manufacturers to scale production without compromising optical calibration stability or signal-to-noise ratio.

Key Features

• Ion-beam etched groove profiles—including quasi-sinusoidal and blazed sawtooth geometries—optimized for specific wavelength bands and polarization states
• Type IV aberration-corrected flat-field concave gratings, enabling direct imaging onto linear or area-array detectors without additional collimating optics
• UV-enhanced diffraction efficiency (>75% at 200 nm) with integrated MgF₂ or Al+MgF₂ coatings for long-term environmental stability
• Low stray light performance (<10⁻⁵ relative intensity at ±5 nm from central wavelength), validated per ISO 14644-1 cleanroom handling protocols
• Thermally stable substrates including fused silica, ULE® glass, Zerodur®, and low-expansion ceramics—qualified for operation from cryogenic to 80°C ambient conditions
• Full traceability per ISO 9001:2015; each batch includes metrology reports covering groove density uniformity (±0.02 gr/mm), surface flatness (λ/20 PV), and coating adhesion (ASTM D3359)

Sample Compatibility & Compliance

These gratings support a broad range of spectroscopic architectures: Czerny-Turner, Paschen-Runge, Ebert-Fastie, and Offner configurations. They are compatible with CCD, CMOS, InGaAs, and photodiode array detectors. All substrates and coatings comply with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. For instruments deployed in pharmaceutical QC labs or clinical diagnostics, gratings can be supplied with full documentation packages aligned with FDA 21 CFR Part 11 requirements—including electronic audit trails for calibration history and material certifications.

Software & Data Management

While the grating itself is a passive optical component, HORIBA provides comprehensive optical design support files (Zemax .ZAR, CODE V .SEQ, and ASAP .ASD formats) for seamless integration into system-level modeling workflows. Metrological data—including measured efficiency curves, wavefront error maps, and polarization-dependent loss (PDL) profiles—is delivered in standardized HDF5 format, enabling automated import into LIMS or instrument firmware calibration routines. Custom serialization and QR-code labeling options are available for lot-level traceability within GMP-compliant manufacturing lines.

Applications

• ICP-OES and ICP-MS spectrometers requiring high-resolution elemental line separation in 160–800 nm range
• Portable Raman analyzers operating at 785 nm or 1064 nm excitation wavelengths
• UV-Vis-NIR liquid chromatography detectors (e.g., HPLC-DAD systems) demanding flat-field response across 190–1100 nm
• Spark-OES metal analyzers where thermal shock resistance and long-term groove integrity are critical
• Fluorescence lifetime spectrometers requiring high UV throughput and minimal out-of-band leakage
• Environmental monitoring platforms for real-time water quality (TOC, nitrate, phosphate) and gas-phase pollutant detection (NOₓ, SO₂, VOCs)

FAQ

What is the minimum order quantity (MOQ) for OEM volume-production gratings?
Standard MOQ is 500 units per configuration; lower volumes may be accommodated for qualification lots under NDA.
Can HORIBA provide custom groove density gradients or non-uniform line spacing?
Yes—holographic master recording and ion-etching allow controlled groove density variation (e.g., for astigmatism correction or spectral compression) within ±0.5% linearity tolerance.
Are these gratings suitable for vacuum-ultraviolet (VUV) applications below 120 nm?
Qualified fused silica and silicon carbide substrates with lithium fluoride overcoating are available for VUV use; contact engineering support for spectral efficiency validation reports.
Do you offer mounting hardware or kinematic alignment fixtures?
Standard kinematic mounts (e.g., three-point flexure bases) and custom-designed holders with thermal expansion matching are available as optional accessories.
How is long-term stability verified for field-deployed instruments?
Accelerated aging tests per MIL-STD-810G (Method 502.6, Temperature Shock) and ISO 10110-7 (surface degradation) are performed on representative samples from each production lot.
