500-1064nmLaser rotator/Precautions for using laser isolators:
1. Ferromagnetic objects should not be placed near optical isolators.
2. Do not attempt to disassemble the Faraday rotor/The magnetic casing of the isolator. May cause serious damage.
3. Reflection of blocked light beams from input and output polarizers.

When there is laser radiation, operators cannot directly observe the optical path through the equipment.
fiveHazards caused by external magnetic fields. If there are any magnetic sensitive implants (such as pacemakers) present, it will have an impact.6. The external magnetic field of the optical isolator can suck in ferromagnetic objects and damage the optical components inside the equipment
,External magnetic fields have an impact on magnetic sensitive equipment.500-1064nm laser isolator, also known asEOTIsolators, Faraday isolators, Faraday optical isolators, EOT Faraday optical isolators, TORNOS Faraday optical isolators, 500-1064nm isolators500-1064nmFaraday optical isolators, etc. The wavelength of the laser isolator is adjustable, achieved by using two series isolators
60 dBEquipped with installation clips, all isolators include a beam escape port, high transmittance, 500-1064nm isolators with optional compact design models.EOT 45of 45TORNOSFaraday rotator can rotate the plane of polarized light forward° and rotate in the opposite directionNon reciprocal rotation of degrees while maintaining linear polarization of light. When placed between cross polarizers, the Faraday rotator becomesEOT
Optical isolator.500-1064nmThe typical structure of Faraday optical isolator is shown in the following figure:
The TORNOS Faraday isolator is essentially a one-way light valve that provides high transmittance in the forward direction and strongly attenuates any backward propagating light, effectively protecting the laser diode from the harmful effects of back reflection.500-1064nmThe optical isolator is shown in the following figure:
TORNOS Faraday optical isolators can be ordered together with dichroic glass polarizers to minimize device size for low-power applications, or can be ordered together with polarizing beam splitters and cubic polarizers for applications that require maximum transmittance and power levels that do not allow the use of dichroic glass polarizers. By aligning the output polarizer vertically with the backward propagating light, it is possible to500-1064nmMaximizing isolation within the available wavelength range of an optical isolator.Pulse fiber lasers have become the main laser source in metal marking and engraving. The processed workpiece can cause laser reflection, resulting in reduced beam quality, poor marking or engraving quality, damage to the laser itself, and so on. As shown in the figure below, back reflection can reach a very high level, approaching in some cases90%
