What Gigahertz Optik does

Gigahertz Optik GmbH is a German manufacturer founded in 1985 and headquartered in Türkenfeld near Munich, specializing in optical radiation measurement equipment across the UV, visible, and near-infrared spectral range (200 nm to 1800 nm). The company designs and produces spectroradiometers (BTS2048 series), spectral light meters (LIGHTmetric ONE, BTS256-EF), modular integrating spheres from 8 mm to 1.2 m in diameter, uniform light sources, and diffuse reflectance standards. Its core technological differentiator is the proprietary BiTec sensor, which combines a photodiode with a back-thinned CCD diode array to deliver high dynamic-range, radiometrically and spectrally accurate measurements, complemented by remote-controlled filter-wheel stray light suppression. The company operates an ISO/IEC 17025-accredited calibration laboratory (DAkkS D-K-15047-01-00) that provides traceable spectral sensitivity and spectral irradiance calibration, and offers precision contract measurement services performed by its technical team.

The company sells directly to B2B customers through its website, a dedicated sales team, and a wholly-owned US subsidiary (Gigahertz-Optik, Inc.). Pricing is quote-based and not publicly disclosed, reflecting the custom and configurable nature of many systems. Gigahertz Optik is part of the Berghof Group, a medium-sized German conglomerate that provides corporate infrastructure and long-term planning stability. Customer segments include LED manufacturers, UV radiation and disinfection monitoring (including UV-C), solar energy and PV testing, laser and photomedicine, image sensor characterization (EMVA1288, IEEE4001), and light hazard assessment for occupational safety — all of which depend on traceable, low-uncertainty optical measurements.

Revenue streams are split between hardware sales (instruments, integrating spheres, light sources, accessories), calibration services from the accredited laboratory, and contract measurement services. Recent strategic activity centers on product launches in 2026 (LIGHTmetric ONE app-controlled spectral luxmeter, VL-3708 precision illuminance sensor) and entry into EURAMET-funded climate metrology research, while maintaining operational continuity under the stable Berghof Group ownership.

Direct peers

• Avantes: Avantes produces fiber-optic spectrometers and modular spectral sensing platforms for UV-VIS-NIR, directly competing with Gigahertz Optik's spectral light meters and spectroradiometers in laboratory and OEM integration contexts.
• Labsphere: Labsphere manufactures integrating spheres, uniform light sources, and reflectance standards—directly overlapping with Gigahertz Optik's modular integrating spheres (8 mm–1.2 m) and uniform light source product lines.
• StellarNet: StellarNet offers compact fiber-optic spectrometers and calibrated light sources for UV-VIS-NIR measurement, serving the same LED-manufacturing, research, and solar-application customers as Gigahertz Optik.
• Bentham Instruments: Bentham specializes in monochromators and double-monochromator spectroradiometers for UV-VIS-NIR light measurement, competing directly in solar-radiation, photobiological, and reference-grade spectroscopy applications.
• International Light Technologies (ILT): ILT manufactures radiometers, photometers, and detectors for UV-VIS-NIR light measurement, alongside calibration services—a direct product-line overlap with Gigahertz Optik's light meters, UV-VIS-NIR radiometers, and ISO 17025 calibration offering.
• Konica Minolta Sensing: Konica Minolta's Sensing Business Unit manufactures spectroradiometers, illuminance meters, and color/luminance measurement instruments—directly comparable to Gigahertz Optik's BTS2048 series, BTS256-LED Tester, and LIGHTmetric ONE product families.

Broad incumbents

• Edmund Optics: Edmund Optics is a broad optics supplier that also distributes integrating spheres, optical sensors, and measurement components—an indirect competitor whose catalog overlap pressures Gigahertz Optik's standard-product pricing.
• Thorlabs: Thorlabs supplies a broad photonics-equipment catalog spanning optics, lasers, detectors, and spectral measurement instruments, offering Gigahertz Optik product categories as part of a much wider portfolio distributed globally.
• Hamamatsu Photonics: Hamamatsu is a broad incumbent in photonics, manufacturing photodiodes, spectroradiometers, and optical sensors across many wavelengths. Its light-measurement line competes with Gigahertz Optik from a much larger R&D and product-portfolio base.

Emerging players

• Ocean Insight: Ocean Insight (formerly Ocean Optics) develops miniature spectrometers, spectral sensors, and light-measurement modules for OEM and embedded use cases—providing an emerging, miniaturized alternative to Gigahertz Optik's bench-form-factor instruments.
