Highlights: ultra short throw 0.21:1, pixel shifting 4K, 4200 lm Has rim blending function, easily display huge screen High-efficiency optical engine design and laser light source module
are free of replacement for 8 years; Native eye protection-diffuse light source, removes harmful blue
light, prevents glare, relieves visual fatigue, clear eye
protection and healthier. Intelligent core-the built-in system covers four main teaching
scenes: whiteboard, textbook, courseware, and review, and provides
various intelligent tools to create an immersive interactive
classroom. Application: Create adaptive application scenarios based on different needs,
such as future classrooms, mobile offices, home theaters, etc. model | SJ-42KL | Main parameters | Projection System | DLP 0.47" | Resolution | 3840*2160 (4K) | brightness | Typ 4200lm | Uniformity*2 | ≥92% | Contrast*2 | Typ 1100:1 | Projection ratio | 16:9 | Sound Output | 8W X 2 | Light source type | type | Laser light source | life | Standard mode: 20,000 hours Energy saving mode: 25,000 hours | Projection lens | type | Fixed focal length lens | Fno. | 2.0±5% | Zoom ratio | 0 | Throw Ratio | 0.21±0.02 | Throw distance | 390mm ~ 584mm (zoom range, best @ 488mm) | Displayable colors | 1.07 billion colors (10 bit) | Off-axis | 147% +6.5%/-3.5% | Light Leakage | <= 0.3 Lux in 0lux darkroom @ 100" black screen and @ outside
