Optical flat

Double Surface Optical Flat/Optical Windows
Advanced Optics offers in stock fused silica double sided optical flats that may also be used as optical windows. Fused silica offers superior transmission characteristics, a high degree of purity, exceptional environmental durability, and a low coefficient of thermal expansion.
Dual Surface Optical Flats/Optical Windows are an excellent choice when an optical system requires separation between two environments while passing a specific wavelength(s) of light or for demanding interferometry requirements.

Optical Flat Certification

Advanced Optics optical flats are measured using either a master test flat traceable to the National Institute of Standards and Technology (NIST) or peak to valley using a Zygo Interferometer.

Ikki yuzli optik tekis/optik oynalar
Advanced Optics kompaniyasi optik oynalar sifatida ham ishlatilishi mumkin bo'lgan ikki tomonlama optik plastinalarni taklif qiladi. Eritilgan silika yuqori o'tkazuvchanlik xususiyatlarini, yuqori darajadagi tozaligini, ajoyib ekologik chidamliligini va past issiqlik kengayish koeffitsientini taklif etadi.
Ikki sirtli optik tekislar/optik oynalar optik tizim yorug'likning ma'lum bir to'lqin uzunligi (lar)ini o'tkazishda ikki muhitni ajratishni talab qilganda yoki interferometriya talablarini talab qilganda ajoyib tanlovdir.
Optik tekislik sertifikati
Advanced Optics optik tekisliklari Milliy Standartlar va Texnologiyalar Instituti (NIST) tomonidan kuzatilishi mumkin bo'lgan asosiy sinov tekisligi yoki Zygo Interferometer yordamida tepadan vodiygacha o'lchanadi.
