The two-dimensional color analyzer CA-2500 adopts XYZ filters and high pixel CCD that are comparable to human visual effects, and can accurately and high-resolution measure the brightness distribution and chromaticity distribution of various displays such as smartphones and tablets. The dedicated software used fully considers usability, and users can complete the entire process from measurement to data analysis and evaluation in a short time through simple operations, greatly improving measurement efficiency. It can play an important role in development evaluation, detection, and other aspects.
Main uses
◆ Uniformly measure the brightness and chromaticity distribution of multiple small and medium-sized LCD panels and organic EL panels
◆ Measure the brightness and chromaticity distribution of individual large LCD panels and organic EL panels
Measure the brightness distribution within the illumination range
Measure the brightness and related color temperature distribution of various luminescent materials
Measure the brightness distribution of vehicle instruments
main features
Expand the measurable range of low brightness
The minimum measurable brightness is 0.05cd/m2, which is twice that of traditional models (CA-2000).
Improving durability
The number of measurable times has significantly increased, about 5 times that of traditional models (CA-2000).
Using XYZ filter sensors, sensitivity comparable to human eyes
The two-dimensional color analyzer CA-2500 uses an XYZ filter (which has spectral sensitivity very close to the CIE 1931 isochromatic function), and compared to the RGB color separation filter used in digital cameras and other devices, it can measure brightness and chromaticity similar to human eye sensitivity.
Equipped with lenses suitable for various objects and purposes
The equipped lens group includes three types of lenses: standard, wide-angle, and telephoto (with macro connection ring). Users can choose the most suitable lens according to different measurement objects and methods.
Complete factory calibration
According to the different types of lenses or focal points, each built-in optical filter has undergone comprehensive factory calibration.
Regardless of the size, brightness, and measurement method of the measured object, users can immediately perform high-precision measurements after purchasing the two-dimensional color analyzer CA-2500.
For the flash light source of PDP and OLED TV products, high-precision measurement can also be carried out
For display devices and pulse emitters, synchronous measurements can be made by inputting frequency values (4-2000Hz).
Standard new software CA-S25w with good operability
This software has functions such as auxiliary focusing, auxiliary positioning, and automatic detection, so users do not need to perform tedious measurement preparation work.
Standard SDK (Software Development Kit)
The two-dimensional color analyzer CA-2500 is equipped with an SDK that can be used for user software development, allowing for efficient creation of independently developed software.
The main measurement distance corresponds to the measurement size (the measurement size is the length in the horizontal and vertical directions)
