We are manufacturing parallel plane substrates with a parallelism of 5 seconds and optical flats with a surface accuracy of λ/20!
We would like to introduce the "Substrates/Windows/Filters" that we handle. In addition to coated products such as anti-reflective films, we also offer high-precision polished products for applications like mirror substrates, with a lineup of "Parallel Plane Substrates/Cylinders." Parallel plane substrates are mainly used for adjusting optical path lengths. They can be shaped as round, square, multi-faceted, and can also be processed with steps. 【Parallel Plane Substrates/Cylinders Specifications】 ■ Dimensions (Effective Diameter Length): φ5 to φ200mm ■ Parallelism: ±5 arc seconds and above ■ Surface Accuracy (λ = 633nm): λ/20 and above ■ Dimensional Tolerance: ±0.2mm and above ■ Others: Various AR coatings and various filter coatings *For more details, please refer to the related links or feel free to contact us.
