Custom Beamsplitters & Dichroics
- Durable IBS coatings for precision specs and stability
- Dichroic mirrors with R >99% at λ1 and T >98% at λ2
- Anti-reflection coating with R <0.1%
PPC strives to deliver precision laser optics as specified and on time. We take pride in coming up with creative solutions quickly—often supplying prototype parts within a few days. Our highly trained technical sales team will work with you from design through final production, and our production team will deliver parts when you need them at prices that you can afford.
Among the many diverse custom optical components that PPC offers are diode-pumped Nd:YAG resonator mirrors, 50/50 non-polarizing beamsplitters and thin-film plate polarizing beamsplitters. For all the optical components we provide, we use only ion-beam-sputtered (IBS) coatings because IBS coatings are significantly more dense, durable, and rugged than conventional coatings. The IBS coating process is both accurate and repeatable, resulting in precision coatings that are easy to clean, chemically resistant and insensitive to moisture and other environmental factors.
Call us for more information on custom high-energy narrowband and broadband beamsplitters and beamsplitter cubes for wavelengths from 250 nm to 3000 nm. High-energy ion-beam-sputtered thin films that are accurate, durable and environmentally stable are our forte, and we can turn them around in as little as 48 hours!
