Spectroscopy detection
Choose a spectral CCD or linear array when you need a complete spectrum in one acquisition, or a single-point detector for a scanning monochromator and targeted wavelength measurements.

Spectroscopy CCD; peak QE specified at 800 nm
A deeply cooled 2048 × 264 scientific CCD detector head with a 30.7 mm-wide active spectral axis, 15 µm pixels and peak quantum efficiency of 95% at 800 nm.
Best suited to
Raman, fluorescence, photoluminescence and other low-light spectrograph readout.
0.85–2.2 µm, model dependent
A 512-pixel InGaAs linear-array detector family for spectroscopic measurements from the near infrared into the extended NIR, with three wavelength-range configurations.
Best suited to
NIR spectrographs, material analysis and spectral acquisition where a full wavelength band is captured at once.
200–1100 nm, model dependent
Large-area silicon photodetectors in UV-enhanced and blue-enhanced versions, with current output and spectral response extending to 1100 nm.
Best suited to
UV–NIR power, responsivity and monochromator-based measurements requiring a large active area.
185–900 nm, tube dependent
Light-tight photomultiplier detector housings with multiple tube options for high-sensitivity UV–visible spectroscopy and direct coupling to Omni-λ spectrographs.
Best suited to
Very weak signals, wavelength scanning and photon-sensitive monochromator measurements.
800–2600 nm, model dependent
Three-millimetre active-area InGaAs detector options covering standard and extended near-infrared spectral measurements with current output.
Best suited to
Single-channel NIR spectroscopy, scanning monochromators and detector-response measurements.
0.8–3.2 µm, model dependent
Room-temperature lead-sulfide detector modules for near- and mid-infrared scanning measurements, with integrated gain selection and voltage output.
Best suited to
Cost-conscious NIR/MIR wavelength scanning without cryogenic cooling.
800–2600 nm, model dependent
Two-stage thermoelectrically cooled InGaAs detector heads covering the standard and extended near-infrared bands, with current output and regulated −40 °C detector operation.
Best suited to
Low-noise NIR scanning measurements that benefit from TE cooling without liquid nitrogen.
1–5.5 µm
Liquid-nitrogen-cooled indium-antimonide detector heads in general-purpose and high-speed configurations, including a model with an integrated preamplifier.
Best suited to
Sensitive mid-infrared spectroscopy and faster measurements up to 5.5 µm.
2–22 µm, model dependent
Liquid-nitrogen-cooled mercury-cadmium-telluride detector heads with four long-wavelength cut-off options plus a high-speed 12 µm configuration.
Best suited to
Sensitive mid- and long-wave infrared spectroscopy, including extended measurements to 22 µm.
Selection guide
| Detector format | Typical role | Available range | Cooling approach |
|---|---|---|---|
| CCD & linear array | Capture a wavelength band in one acquisition | Visible/NIR to 2.2 µm | TE cooling |
| Single point | Scan wavelength with a monochromator | 200 nm to 22 µm | Room temperature, TE or LN₂ |
| PMT | Prioritize sensitivity for very weak UV–visible signals | 185–900 nm, tube dependent | Room temperature |
Spectral coverage and cooling are model-dependent. Confirm the complete optical and electrical configuration before ordering.
Detector choice depends on the monochromator focal plane, wavelength range, signal level and acquisition method. We can review the full source–sample–spectrograph–detector chain.
