Fiber Laser Bandpass Filter

It is used to block out unwanted noise signals in edfas and fiber laser systems.

Fiber laser bandpass filter.

Our premium bandpass filters are hard coated for higher transmission and are more durable and longer lasting than our standard bandpass filters. Narrow 0 8 nm bandwidth. It is used to block out unwanted noise signals in edfas or fiber laser systems. The components are characterized with high isolation low insertion loss high return loss excellent environmental stability and high power handling capability.

The bandpass filter is a micro optics device based on environmentally stable thin film filter technology. It consists of two multi cavity thin film filters with 18 nm bandpass with very steep walls. This advantage is accompanied by a loss of transmission of approximately 20 30. Our laser line bandpass filters cover most of the common laser lines and feature excellent out of band blocking of less than 0 01 10 4.

Adjustment of the center wavelength is accomplished by tilting the bandpass filter with a high precision micrometer. Our bandpass filters feature a dielectric stack fabry pérot interferometer design. Bandpass imaging filter in ball lens is simple and widely tunable based on frustrated total internal reflection a tunable filter is compact has a large range and can be easily designed into optical systems. Sensitivity to angle of incidence.

A bandpass filter is characterized by a defined passband onto which cut off regions are connected on both sides. This would allow measurements from the uv to the nir range to be taken. Unblocked standard laser line filters blocking area with 0 85 1 15 x cwl have a transmission of 60 85. Applications include sideband noise suppression in erbium doped fiber amplifiers edfas and for use in tunable laser transmission systems.

Manually tunable optical filter dicon s manually tunable optical bandpass filter is used to manually adjust the center wavelength of a narrow optical bandpass filter over a 30nm wavelength range centered at 1550nm. Tunable bandpass tunable wavelength filter modules tbtfm enable simultaneously varying the bandpass and center wavelength of the filter. The bandpass can be varied from 2 nm to 18 nm and the center wavelength can be tuned from 1525 nm to 1560 nm. Newport s tunable bandpass fiber optic filter is used to adjust the center wavelength of a narrow passband within a 30 nm range around 1550 nm.

All standard laser line filters can also be delivered blocked.
