NLIR Mid‑Infrared Spectroscopy Solutions

Neeyal EnviroSolutions is the exclusive Pan‑India distributor for NLIR (Denmark), pioneering "Mid‑Infrared Spectroscopy with Ease" via advanced upconversion technology.

Product Lineup

MIDWAVE Spectrometer

Band: 2.0 – 5.0 μm (2000–5000 cm⁻¹) optical range
Speed: Capture full spectrum in milliseconds; up to 400 Hz readout (kHz variants available)
Resolution & Sensitivity: ~6 cm⁻¹ resolving power, sensitivity down to 5 pW/nm (dark noise ~11 counts)
Design: Fibre-coupled (SMA‑905) grating spectrometer. Detects via upconversion to the visible/NIR region using CMOS array — no cryogenic cooling needed
Applications: Gas and liquid sensing, optical coatings, plastic sorting using AI, combustion monitoring, high-speed spectroscopy, etc.

Bundle Spectrometer System

Configures the NLIR upconversion module (Spektrum or Tune) with standard VIS/NIR spectrometers (e.g., Avantes or Wasatch brands) for cost-efficient MIR detection
Offers ultra-fast readout up to 1 kHz or 130 kHz, with resolution options from 3 to 2.5 cm⁻¹

Custom Spectrometer Solutions

Usable bandwidth from ~1.7 μm to 5.0 μm, with flexible configuration of exposure time, resolution, and spectral range to suit bespoke research and industrial applications

Key Technical Highlights

All instruments based on upconversion technology: convert mid‑IR radiation into near‑visible/NIR wavelengths using a nonlinear LiNbO₃ crystal and 1064 nm laser field, enabling high-speed silicon detection with superior signal-to-noise ratio

Eliminates thermal noise and removes the need for cryogenic cooling; offers exceptional sensitivity and real-time spectral feedback
