Product Information
Product Overview
Characteristics of relative spectral sensitivity
As a characteristic of the relative spectral sensitivity of the light receiving part of the luminance meter, an ideal state should be the standard spectral optical efficiency V (λ) * for human visual perception.
main purpose
Measure the brightness of CRT, LED, EL, etc
Measurement of road lighting and tunnel lighting
Identification of measuring railway systems
Measure the markings of motor vehicle lanes and airport systems.
Measurement of general lighting, outdoor billboards, etc
Measurement of luminous parts of various lighting facilities and appliances
Various research and measurement experiments
Measure the brightness of various measuring instruments
Main features
The optical system adopts a single lens reflex non expanding tube body.
When measuring, use a single lens reflex method with no deviation between the actual measurement field and the measurement field inside the viewfinder. Only measure within the measurement range,
It can avoid the influence of light sources outside the measurement range on the optical system of non expanded tube bodies.
It is a point based measurement that can capture small parts.
The measurement angle of LS-100 is 1 °, while LS-110 is 1/3 °, so it can measure the brightness of small parts. Additionally, by using close-up shots (sold separately),
LS-100 can measure a diameter of 1.3mm,LS-110 can measure the brightness of small areas within 0.4mm.
Can input color correction coefficient, with a wide measurement range.
As an arbitrary calibration mode, users can input any calibration reference that can be recalibrated on their own standard brightness,
It is also possible to use multiple luminance meters in the * state to implement precise luminance management by inputting a color modification coefficient that modifies the indication difference to a specific light source.
Can perform brightness ratio measurement and peak measurement.
The measurement values can be selected according to different usage purposes, including instantaneous brightness value, peak brightness value, and brightness ratio.
Bidirectional communication can be achieved through RS-232C.
Through the standard equipment of RS-232 interface, measurement data output and computer control can be carried out.
Small and lightweight design, powered by one 9V stacked dry battery.
Power can be provided from the data printer DP-10. ）
