Attenuating Mono Fiber-optic Patch Cords
Fiber-optic patch cords with an integrated attenuating filter are ideal for applications where optical power coupled into a fiber is too high, i.e. fiber photometry excitation. Addition of attenuating filter does not affect light distribution inside the optical fiber, only transmission is reduced. Different optical fibers or attenuating factors are possible.
- For attenuating patch cords, optical transmission is specified for visible light, and measured at a 465 nm wavelength. Please note that for a 405 nm wavelength (UV), the transmission value is about half of the specification for visible light.
- Other fiber-optic lengths and jackets are available on custom request.
- An attenuating filter can also be integrated to Branching Fiber-optic Patch cords on custom request.
