Practical, plain-language explanations of the optics we manufacture — and the specifications that matter when you specify them.
Zero-Order vs. Multiple-Order Waveplates: How to Choose
Both change the polarization of light. Only one stays accurate when your lab warms up. Here is the difference in plain terms.
Read articleWhy Air-Spaced Waveplates Win for Lasers
Cemented plates can delaminate. Contacted plates drift. Air spacing removes both failure modes — and improves alignment accuracy.
