This computer system gives automated MTF and quantitative resolution measurement. It reduces subjectivity in image analysis.

The modulation transfer function (MTF) is a numerical and graphical representation of an optical system's ability to produce a faithful and accurate image of an object.

5. Colorimeter

The equipment measures the colorimetric quantities in the whole visible spectrum of light sources, displays and textures

The equipment measures the colorimetric quantities in the whole visible spectrum of light sources, displays and textures. It can also measure the radiometric and photometric quantities.

6. Integrating Sphere

For measuring the total power or luminous flux of LED

Integrating Sphere
Integrating Sphere

  • The integrating sphere measures the total power or luminous flux of LEDs. 
  • It characterizes the brightness of LED for an effective optical design.

7. LED Goniophotometer

The Goniophotometer measures the luminous intensity of an LED at all different emission angles and generates a radiation pattern

LED Goniophotometer
LED Goniophotometer

  • The LED Goniophotometer measures the spatial radiation pattern of the LED 
  • It quantifies the luminous intensity of the LED at different angles

8. High Sensitivity Digital Optical Power Meter

The Power Meter provides interchangeable measurement sensor head with a built-in IR viewing target for allowing easy alignment

9. Optical Beam Profiler 

The optical beam profiler provides high precision analysis of beam quality and spatial power distribution and inspection for continuous and pulsed laser beams

10. Junction Temperature Tester 

The Junction Temperature Tester measures the junction temperature of LEDs
