기능

• Both sides of the glass substrate are polished in parallel.
• It can be used as a substrate for coating evaporated films with custom beam splitters, windows, etc.
• A BK7 type parallel planar substrate that can be used in the visible and infrared regions.
• For those with a high degree of parallelism, the angle of the transmitted beam does not change when a parallel plane substrate is inserted perpendicularly into the optical path of the laser.
• High surface accuracy can also be used as an alternative to Newton's original.
• Wedge boards (WSB/WSSQ/WSSQK) are also available to prevent backside reflections.
• * The parallel plane substrate loses 10% due to the reflection of the front and back surfaces.
• * Surface accuracy guarantee data is not attached to the product.
