Konica Minolta Sensing Americas, Inc. (Konica Minolta) highlights its progressive technology at Photonics West booth #3181 with its display measurement product line. Konica Minolta’s latest advanced high-sensitivity probes measuring ⌀27mm (model CA-VP427A) and ⌀10mm (model CA-VP410A) offer the same respected quality and performance expected from our full-line of probes but at a more sensitive threshold.
The CA-VP427A (advanced high-sensitivity probe) has a measuring area diameter of ⌀27mm and is applicable for displays sized at 5 inches and above with best repeatability for OLED displays evaluation such as smartphones and TVs. With its acceptance angle of +/- 2.5 degrees. The updated features include an accuracy guaranteed range for luminous intensity (Lv) of 0.0003 to 5000 nits.
The CA-VP410A (advanced high-sensitivity probe) has a measuring area diameter of ⌀10mm and is applicable for displays sized between 2 and 10 inches and above, with best repeatability for OLED displays such as smartwatches. The updated features include an accuracy guaranteed range for luminous intensity (Lv) of 0.0001 to 3000 nits.
Konica Minolta Sensing’s reputable line of probes also include our ⌀2.1mm (model CA-VP402), ⌀4mm (model CA-VP404) and viewing angle characteristics (CA-VP410T) of displays. These progressive instruments for AR/VR microdisplays and curved OLED displays for Lvxy/u’v’, FMA, JEITA,VESA and flicker use the new CA-410 probes to measure ⌀2.1mm, ⌀4mm and viewing angle characteristics.
The CA-VP402 (small spot probe ⌀2.1mm) has a measuring area diameter of ⌀2.1mm. The dedicated optical system and operation algorithm provides both guaranteed accuracy at low luminance and small measurement area. Suitable for applications requiring small-area measurements ranging from low luminance measurements, such as for gamma adjustment of micro-OLED, to that of high-speed, high-accuracy measurements. The CA-VP404 (small spot probe ⌀4mm) has a measuring area diameter of ⌀4mm. The guaranteed accuracy from 0.004 cd/m2 enables high-speed, high-accuracy measurements of small areas such as smartwatch OLEDs, smartphones, and small APL (average pixel level) windows.
Also available in the collection is the the high sensitivity probe (⌀27mm, ⌀10mm) which is primarily used for OLED displays and offers superb chromaticity repeatability on lower-level luminance displays. The ⌀10mm long-working distance probe (model CA-VP410T) has a measurement distance of 200mm to the sample and is extremely valuable in viewing angle measurements. Its ability to take multi-angle measurements of in-vehicle displays or smartphone OLEDs is due to its ability to measure displays regardless of its directionality. In addition, the long working distance probe is used in applications when distance from the item being measured is important. This valuable feature is used in production measurement systems when the need to avoid collisions with the item being measured is imperative.
These probes are compatible with Konica Minolta’s Display Color Analyzer CA-410 instrument. The CA-410 is used for high-speed measurement of precise luminance, chromaticity and flicker of HDR displays, including curved OLED screens. Users can accurately measure and adjust the chromaticity and white balance of displays that have a wide color gamut. It can also easily integrate into an existing automatic measurement system and capture flicker measurement with the wider frequency measurement range that covers all types of displays.
