Product catalog summary
Introduction
The LDM-1901 is a sophisticated optical measurement device designed to comply with IEC 62471:2006 and EN 62471:2008 standards for photobiological safety classification of non-coherent optical sources. It is essential for CE marking under the EU's Artificial Optical Radiation Directive 2006/25/EC.

Specifications and Features
The LDM-1901 telescope is used with the BTS2048-VL-TEC spectroradiometer to measure spectral radiance and irradiance, crucial for assessing risks to skin, cornea, and retina. It covers a spectral range from 300 nm to 1050 nm and is suitable for various LED types. The device features interchangeable apertures for different fields of view and a camera-based viewfinder for easy alignment.

Measurement Capabilities
The device measures optical hazards in the UV (200 nm to 400 nm) and visible spectrum (300 nm to 1050 nm). It is particularly effective for assessing blue light hazards in white LEDs. The BTS2048-UV spectroradiometer complements it for UV hazard measurements.

Calibration and Quality Assurance
Gigahertz Optik provides factory calibrations with high traceability, ensuring international acceptance of measurements. The LDM-1901's calibration is aligned with DAkkS accredited standards.

Applications
The LDM-1901 is used for risk group classification of non-laser sources, determination of blue light and retina hazards, and UV risk group classification. It is configurable with various detectors for specific hazard assessments.

Purchasing Information
The product is available in different models and configurations, with separate calibration options. Accessories and adapters are also available for enhanced functionality.

Contact and Support
Gigahertz Optik offers comprehensive technical consulting, after-sales support, and calibration services. They can be contacted via phone or email for inquiries and support.

LDM-1901 -2

The introduction of IEC 62471:2006 was originally prompted by the need to remove LEDs from the existing laser safety standards. Within Europe, EN 62471:2008 specifies the photobiological safety classification of noncoherent optical sources. It is a harmonised standard under the low voltage directive and is therefore required for CE marking of products. To protect workers from the possible harmful effects of optical radiation, the EU introduced the Artificial Optical Radiation Directive, 2006/25/EC, which became law in all member states from April 2010. The directive makes reference to EN 62471:2008...

• The BTS2048-VL-TEC with the LDM-1901 telescope attached measures the spectral radiance for the risk classification of retinal hazards. Of particular importance to white light LED sources is the assessment of blue light hazard which is determined from spectral radiance measurements over the 300 nm to 700 nm spectral range. For general lighting service products IEC TR 62778 "Application of IEC 62471 for the assessment of blue light hazard to light sources and luminaires" is most relevant. Spectroradiometer for Determining UV Hazard 200 nm to 400 nm. The measurement of UV hazards in the 200 nm...

To assess the blue light and thermal hazards to the retina, different fields of view are specified. The LDM-1901 is equipped with changeable apertures for 100 mrad, 11 mrad and 1.7 mrad field of view. Camera-based Viewfinder To align the meter, the LDM-1901 is equipped with an integrated camera whose image is displayed as a window within the application software. This simplifies the alignment compared to a viewing eyepiece and, importantly, eliminates any danger to the user's eye. Calibration In addition to the high specification and the correct operation of the measurement device, the quality...
