Thermal Sensor Absorption Spectra
- For General Broadband Optical Power Measurements
- Ø12 mm - Ø25 mm Sensor Area
- Fast Response Time
- Broadband Coatings with Flat Response over a Large Wavelength Range
- Compatible with the PM200, PM100D, PM100USB, PM100A, and PM320E Consoles
The S3xxC Standard Thermal Power Sensors are designed for broadband optical power measurements of low (100 µW) to high (200 W) power sources. The broadband coatings used on these thermal sensors feature a flat response over a wide range of wavelengths (190 nm to 25 µm). See the Absorption Spectra.
NIST-traceable response curves are stored in the sensor connector. Aperture sizes from Ø12 mm to Ø25 mm allow easy alignment and measurement of large spot size laser sources. All Standard Thermal Sensors feature SM1(1.035"-40) threading on the front for easy integration into existing cage and lens tube systems in addition to fiber coupling applications.

The S305C Slim Thermal Power Sensor is designed for detecting broadband optical power measurements from 10 mW - 5 W power sources in locations where space and accessibility are at a premium. The broadband coating used on this thermal sensor features a flat response over a wide range of wavelengths (190 nm to 25 µm). See the Absorption Spectra.
NIST-traceable response curves are stored in the sensor connector. The aperture size of Ø10 mm allows easy alignment and measurement of large spot size laser sources. The Slim Thermal Sensor features a SM1 (1.035"-40) threading on the front for integration into existing lens tube systems in addition to fiber coupling applications and 4-40 taps at each corner compatible with the 30 mm cage system. The sensor housing has virtually the same dimensions as a cage plate of the 30 cage system.
Compatible with Devices with External SM1 Threads:
- S120 and S140C Photodiode Power Sensors
- S300 Series Thermal Power Sensors (except S350C & S370C)
- APD110 and PDF10 Series Photoreceivers
