Optical power meter without red light function

For applications requiring precise optical power measurement without a red light, photodiode-based meters like the Artifex OPM500 or standard handheld/benchtop meters from Newport, Thorlabs, and VIAVI are suitable.

Photodiode-

Based Meters

Devices such as the Artifex OPM500 measure optical power using a photodiode, producing a voltage proportional to the incident light without including a red visual fault locator. These meters are highly flexible, offering USB or hard-wire interfaces, multiple gain ranges, auto-null functions, and continuous measurement capabilities. They are ideal for visible and near-infrared wavelengths and can be calibrated for monochromatic sources, ensuring accurate readings without any red light emission.

Handheld and Benchtop Meters

Manufacturers like Newport and Thorlabs offer handheld and benchtop optical power meters that rely on calibrated sensors for precise measurements. These meters can measure across a broad range of wavelengths and powers, and the sensor heads do not inherently include a red light unless paired with a visual fault locator. For example, Thorlabs' PM100 series consoles can be used with standard photodiode sensors without activating any red light function.

Lab and Field ApplicationsVIAVI Solutions provides optical power meters suitable for both lab and field use, including pocket-sized and low-cost models that measure optical power via USB or console interfaces. These devices focus on accurate power measurement and do not require a red light, making them suitable for environments where visual fault locators are unnecessary or could interfere with measurements.

Key Considerations

When selecting an optical power meter without red light: Sensor Type: Choose photodiode or calibrated sensor heads without integrated visual fault locators. Wavelength Range: Ensure the meter covers the wavelengths of interest (e.g., 850 nm, 1310 nm, 1550 nm). Interface Options: USB, BNC, or console interfaces allow flexible data acquisition.

Accuracy and Dynamic Range: Look for meters with high linearity and low noise for precise measurements. Portability: Handheld meters are ideal for field use, while benchtop meters suit lab environments. By focusing on photodiode-based or standard sensor meters from reputable manufacturers, you can achieve accurate optical power measurements without any red light interference.
