GL Opti Sphere

Product catalog summary

Overview: The document provides a detailed technical overview of GL Optic's integrating spheres, which are used for measuring luminous flux and radiant power of various light sources, including LEDs and luminaires. These spheres are compatible with GL spectrometers through direct connections.

Historical Context: Integrating spheres have been a standard in photometry and radiometry since R. Ulbricht's implementation over 115 years ago.

Product Range: The GL Optic spheres come in various sizes, including GL OPTI SPHERE 48, 205, 500, 1000, 2000, and 3000, each designed for specific applications ranging from single LEDs to large luminaires.

Technical Specifications:

Spectral Range: 340 – 1700 nm for all models.
Sphere Material: Varies from aluminum to composite and carbon steel depending on the model.
Inner Coating: High-reflectance Barium Sulfate (BaSO4) with 98% reflection.
Outer Coating: Black or grey textured finish.
Reflectance Properties: 97% to 98% depending on the model.
Auxiliary Light Source: Options include white LED or halogen.
Standards Compliance: Models comply with standards such as EN 62471, IESNA LM-79-08, CIE 127:2007, and CIE S 025/E:2015.

Features:

High reflection BaSO4 coating.
2π and 4π configurations.
Direct connection or SMA fiber-optic spectrometer ports.

Design and Functionality: The spheres are designed with modern materials and calibration technology, offering optimal solutions for measuring luminous flux and radiant power. Larger models include features like hinged frames and electric-powered opening mechanisms.

Dimensions and Weight: The document provides detailed dimensions and weights for each model, ranging from 0.126 kg for the smallest to 1100 kg for the largest sphere.

Technical Sheet All our spheres connect to any GL spectrometer using a direct connection. Integrating spheres have become a standard instrument in photometry and radiometry since R. Ulbricht's practical implementation of the light-collecting cubical box more than 115 years ago. Today, GL Optic produces high reflectance integrating spheres using modern materials such as composite and combining them with the latest calibration technology. They are the optimal solution for luminous flux and radiant power measurement of single LEDs, LED luminaires and modules. Features: ■ Luminous flux and radiant power measurements ■ High reflection BaSO4 coating with 98 % reflection ■ 2n and 4n configurations ■ Suitable for compliance with international standards: EN 62471, IESNA LM-79-08, CIE 127:2007, CIE S 025/E:2015 and others GL OPTI SPHERE 48 Luminous flux and radiant power measurement of single LEDs and other small light sources. Mounts directly on spectrometer. GL OPTI SPHERE 205 Luminous flux and radiant power measurement of LEDs and other light sources GL OPTI SPHERE 500 Luminous flux and radiant power measurement of LED modules and retrofit lamps GL OPTI SPHERE 1000 Luminous flux and radiant power measurement of large LED modules and luminaires GL OPTI SPHERE 2000 Luminous flux and radiant power measurement of large LED modules and large luminaires Radiant power and luminous flux measurements TECHNICAL DATA Spectral range Sphere inner diameter Sphere material Inner coating Outer coating 340 - 1700 nm 48 mm Aluminium Barium Sulfate (BaSO4) high-reflectance material (R98) Black textured finish Barium Sulfate (BaSO4) high-reflectance material (R98) Black textured finish Barium Sulfate (BaSO4) high-reflectance material (R98) Barium Sulfate (BaSO4) high-reflectance material (R98) Black finish Black finish 340 - 1700 nm 2000 mm Carbon steel Barium Sulfate (BaSO4) high-reflectance material (R98) Black textured finish Carbon steel Barium Sulfate (BaSO4) high-reflectance material (R98) Grey textured finish Light measurement solutions
