| Technical Data | |
|---|---|
| Sensor — imaging CMOS matrix system | 4112 x 3008 Pixel Sony-CMOS [ IMX 253 （1,1“）; 12 Bit digital ] |
| Housing dimensions without lenses (H × W × D) | Stable black anodized aluminum housing: 80 mm × 80 mm × 47 mm |
| Weight | Camera housing without lens: 600 g Available lenses: 120 g – 800 g |
| Data interface | Gigabit Ethernet Interface(GigE®) |
| Metrological data | |
|---|---|
| Dynamic range | Single picture measurement: 1:1100 (~ 61 dB) High-dynamic measure (exposure bracketing series): 1:10,000,000 (~ 140 dB) |
| Spectral matching1 | Matched to the V(λ) luminance function for luminance measurement with a full-glass filter |
| Metrological specification | V(λ) [ f1' < 3 %]2 |
| Measuring quantity | Luminance: L (cd/m²)> |
| Measuring range³ | Integration/exposure time from 100 μs to 15 s 1 ms ≈ max. 10,000 cd/m² 3 s ≈ max. 3.3 cd/m² The detection limit4 (f3,0) for all integration/exposure times is about 0.04 % relative to the given maximum luminance value. Higher luminance can be measured using optional neutral density filters. |
| Calibration uncertainty5 |
fix focused lenses ∆L [ < 2% ]
focusable lenses ∆L [ < 2.5% ]
|
| Repeatability6 | ∆L [ < 0.1% ] |
| Measuring accuracy | ∆L [ < 3%] for standard illuminant A |
| Uniformity4 | ∆L [ < 2% ] |
