Frequently Asked Questions

What is a 1064nm TGG Based Optical Isolator and how does it work?
A 1064nm TGG Based Optical Isolator is a passive optical device designed to allow light to pass in one direction while blocking it in the reverse direction, thereby preventing back reflection and back scattering in fiber optic systems. It uses a Terbium Gallium Garnet (TGG) crystal to rotate the polarization of light, ensuring high isolation and low insertion loss, which is critical for protecting lasers and amplifiers in fiber optic communication equipment.
What are the key features of the DK Photonics 1064nm TGG Based Optical Isolator?
The key features of the DK Photonics 1064nm TGG Based Optical Isolator include high isolation, low insertion loss, cost effectiveness, excellent environmental stability, and high reliability. It is available in both polarization insensitive and polarization maintaining versions, with customizable power handling and wavelength options.
What applications are suitable for the DK Photonics 1064nm Optical Isolator?
This optical isolator is widely used in fiber optic amplifiers, fiber optic lasers, test and measurement equipment, and other instrumentation. It is ideal for any application where suppression of back reflection and back scattering is critical to system performance and laser protection.
Can the DK Photonics 1064nm Optical Isolator be customized for specific requirements?
Yes, DK Photonics offers custom solutions for their optical isolators. Customers can request specific fiber pigtails, different operating wavelengths (from 500nm to 2100nm), higher power handling (from 300mW up to 150W or more), and other custom specifications to meet unique application needs.
