Luminance Meter BM-9A

Successor model of Luminance meter BM-9A. Detector unit are detachable, light weight, and small size instrument.

Model: BM-9AC with Head type BM-9A20D :0.01~280,000 cd/m²  BM-9AC with Head type BM-9A10D : 0.1 ~ 2,800,000 cd/m²  BM-9AC with Head type BM-9A02D : 1 ~ 28,000,000 cd/m²  The TechnoOptis BM-9A (specifically the BM-9A20D) is a portable, high-sensitivity luminance meter manufactured by Topcon Technohouse Corporation. It is designed for measuring the brightness of light sources like LCDs, OLEDs, and LEDs, as well as for automotive and outdoor lighting.   The Luminance meter BM-9A is a handy-type luminance meter with a wide measurement range and excellent operational convenience. With newly added 1°measuring field detector, totally three types of detectors(2°/1°0.2°) can handle a wider range of usage. Measurement mode selection using dip switches has greatly improved operational ease. Also, in-line arrangement can be easily dealt with, due to the built-in USB and the separation of the detector and the display unit. There are a wide variety of options, such as extension cable, Attachment lens, etc. [embedyt] https://www.youtube.com/watch?v=zdiV5lLol8g[/embedyt]   Application • Luminance measurement of LCDs, OLEDs, LEDs, etc. • Luminance sensor for robots. • Luminance measurement of street lighting, tunnel lighting, etc. • Measurement of airport lighting facilities, sea route signals. • Transmittance measurement for LCD polarizing plates and various filters. • Measurement of medical lighting. • Illuminance irregularities of automobile license plates. • Luminance measurement of various lighting facilities, etc. • Luminance measurement of Block for guiding visually handicapped person.

• Modular Design: The system consists of a main display unit (BM-9AC) and detachable, interchangeable detector units. ( Head type BM-9A20D/ BM-9A10D/ BM-9A02D )
• Connectivity: Includes a built-in USB port for PC connection, making it suitable for automated production lines and measurement systems.
• Portability: Lightweight and compact, the display unit weighs approximately 130g, while the detector weighs about 220g.
• Power: Typically powered by two AA batteries or a specified AC adapter.

Specifications BM-9A with head type BM-9A20D: The BM-9A20D refers to the specific configuration with a 2° measurement angle detector. 

• Measuring Field: 2°.
• Measurement Range: 0.01 to 280,000 cd/m²  
• Measurement Distance: 350mm～∞
• Accuracy: ±2% of rdg. ±2 digit (0.1cd/m² more) 
• Minimum Measurement Diameter: 9.5mmφ (1.02mmφ)

• Lens cap on objective/eyepiece lens is not required to conduct 0 adjustment. So the BM-9A is easy to operate even when the BM-9A is installed in measurement systems. • Built-in Keyboard enable to calculate luminous intensity. • Response speed are selectable. flicker and waveform can be observed by connecting oscilloscope. • Extension cable (option) enable BM-9A to detach Detector unit and Display unit. • Display unit automatically recognize each detector unit. Maintenance and calibration :  ► We also have calibration certificate attached ( optional ) ► Please re-calibrate after use for a certain period through our purchase store.
