Description
Product Description
- Device for measuring the absorption characteristics of materials or samples at different optical wavelengths.
- Three independent detector channels enable simultaneous measurement of absorption at multiple wavelengths.
- Includes two 45° rightangle mounts for dichroic mirrors, with ±4° adjustable tilt range.
- One detachable SM1toSMA fiber port.
- Filter mounts in front of each channel for fiber applications requiring filtering or power attenuation.
An Optical Absorption Detection Module is a device used to measure how strongly materials or samples absorb light at specific wavelengths. Widely used in optical analysis, spectroscopy, chemical sensing, environmental monitoring, and biomedicine, it quantifies energy loss as light propagates through matter.

Technical Description
An Optical Absorption Detection Module measures wavelength-dependent light absorption by materials or samples. It is widely used in optical analysis, spectroscopy, chemical sensing, environmental monitoring, and biomedicine to quantify energy loss during light transmission.
Core Functions
- Measure absorption properties: Determine absorption strength at various wavelengths to characterize optical parameters such as absorption coefficient and bandgap.
- Quantitative sample concentration: Using the Beer-Lambert Law, the module measures concentrations of target substances in solution, widely applied for detecting chemicals, protein levels, DNA, etc.
- Environmental monitoring and gas detection: Used to measure atmospheric pollutants and gas concentrations (CO₂, NOₓ, etc.) by their wavelength-specific absorption signatures.
- Each module integrates two adjustable dichroic mounts, one fiber port, three SM1 threaded ports, and three filter mounts to form a fixed coupling system supporting both free-space and fiber-to-fiber operation.
- Each SM1-threaded filter mount supports filtering or power attenuation for fiber setups. A sliding insert accepts Ø1” filters up to 6.6 mm thick. Absorptive filters with transmission from 0.01% to 80% are available.
- Dichroic mounts hold Ø1/2” mirrors (≥2.5 mm thick) at 45° to the optical axis, secured by setscrews. Tilt is adjustable ±4° via M5×0.25 fine adjusters operated with a 2.0 mm hex key, with lockable position.
- The input port features an SMA fiber adapter for connecting LEDs or lasers via single-mode or multi-mode fiber. The SM1 internal thread accepts Ø1” plano-convex lenses to collimate light from the input fiber and couple it into output fibers. Compatible with Ø1” lens sleeves, photodiode power probes, and optical detectors.
