功能

• This substrate is used for optical elements that do not require high surface quality, such as simple experiments and illumination optics.
• The surface accuracy is the same as that of a planar substrate for lasers.
• In addition to round planar substrates, square and rectangular planar substrates and parallel planar and wedge substrates with high surface accuracy on both sides are available.
• Planar substrates (OFB/OFBP) are also available, which have less scattered light from the laser.
• * Both sides of the flat board are not coated.
• * The surface of the glass has 3.5~4% reflection.
• * When a flat substrate (back polished surface) is used for transmission, the transmission beam may be slightly inclined.
• * When using with transmission, use (OPB, OPSQ, OPSQK) with parallel plane substrate.
• * Surface accuracy guarantee data is not attached to the product.
