Technical data
| Technical Indicator | Parameter Specification | Indicator Description |
| Dimensional Tolerance | +0.0/-0.2mm | High-precision size control, suitable for automated equipment assembly, reducing assembly gaps |
| Surface Finish | 60-40 | Strict control of surface scratches and pits, stray light suppression rate >98%, improving optical imaging quality |
| Clear Aperture | >90% | High proportion of effective light-transmitting area, avoiding reduced light utilization caused by edge blocking |
| Parallelism | <1 arc min (Angular Minute) | Minimal parallelism error between the two light-transmitting surfaces, reducing optical axis deviation, suitable for high-precision optical systems |
What to specify when you request a quote
- Split ratio — give the R/T ratio and its tolerance.
- Wavelength and polarisation — listed as “200-2000nm”; state the band and whether the split must be polarising or non-polarising.
- Angle of incidence — listed as “0°”; plate splitters are usually used at 45°; give the actual angle.
- Size and geometry — listed as “Customize as Per Demand”; give cube edge or plate size, thickness and wedge if any.
- Surface quality and flatness — quote transmitted wavefront for imaging systems.
