Thermopile Surface Absorber Head Price & Specs

MKS Instruments / Ophir F300A-LP Thermopile Surface Absorber Head Description

Functions

High-power thermopile sensor head designed to measure continuous wave (CW) or long-pulse laser power up to 300W within the spectral range of 0.19-20µm. Features a large 30mm aperture with a spectrally flat broadband absorber coating. Incorporates passive water cooling for thermal management during high-power measurements. Provides high accuracy (±3%) power readings with excellent linearity across measurement range. Equipped with smart plug technology for automatic calibration data recognition when connected to compatible meters. Designed for industrial laser measurement applications, process monitoring, and quality control in manufacturing environments.

Platforms

Compatible with laser measurement applications, operates with Ophir's laser power meters, utilizing a range of wavelengths and power levels; integrates directly with optical benches or test stands for precision laser output measurements, often used in laboratory or industrial environments.

Applications

Laser power measurement, testing high power continuous wave (CW) lasers, monitoring dynamic laser performance, ensuring power stability and consistency, calibrating laser outputs in industrial and laboratory settings, interfacing with laser power meters for precise readings, supporting laser material processing, R&D applications, and laser maintenance operations, adaptable to varying environmental conditions.

Accessories

Requires compatible Ophir power/energy meter mainframe with appropriate input connector. Standard BNC or proprietary Ophir connector interface depending on meter model. Mounting accessories include threaded tripod adapter and magnetic base options. Protective window and calibration certificate typically included. Cable length varies by meter compatibility requirements.

Interfaces

DB-15 (D-subminiature, 15-pin) male port transmits analog thermopile sensor signals and digital EEPROM data. This interface connects to compatible Ophir laser power meters or PC interfaces with a corresponding female DB-15 port for measurement readout and processing.

Specifications

Designed to measure laser power and energy with high accuracy, this thermopile surface absorber head converts incident radiation into thermal energy, generating a voltage proportional to absorbed power. It operates within a vacuum-compatible mechanical housing, connects via standard coaxial cables to data acquisition systems or laser power meters, and interfaces with control software for real-time monitoring. Commonly used in laser research, industrial laser calibration, and high-power laser system testing, it handles continuous-wave and pulsed lasers across a broad wavelength range with robust thermal management for stable, repeatable measurements.
