DHF Faraday Rotators

Four DHF Faraday rotators are listed by operating wavelength. Their cards state a 3.5 mm clear aperture, transmission >98% and a damage threshold of 7 J/cm². The red housing photograph is reused as a series illustration. Rotation angle, test conditions and mounting dimensions are not supplied; select by complete model and the requirements of the actual optical setup.

Models and operating wavelengths

The four options are explicitly labeled for 1064, 1053, 1045 and 1030 nm. Each card reuses a photograph engraved @1064 nm. That engraving does not override the selected model’s stated wavelength or establish interchangeability across all four wavelengths.

Aperture and transmission

All four cards state a 3.5 mm clear aperture and transmission >98%. These are source specifications without test curves, wavelength bandwidth, incidence angle, input polarization or measurement conditions. Rotation angle, angular tolerance and isolation are not provided. DHI isolator ratings such as >35 dB are not assigned to these DHF rotators.

Damage threshold and operating conditions

Each option lists a damage threshold of 7 J/cm² without pulse duration, repetition rate, beam size or test method. This does not establish CW power, peak power or an operating limit for a particular optical setup. Substrate, coating, temperature range and polarization extinction performance are unspecified; obtain data for the intended laser conditions.

Construction, mounting and delivery

Photographs show a red housing, integral mounting feet, a silver circular end section and a small central opening. No dimensioned drawing, mounting interface, optical-axis height, adjustment method or rotation-direction definition is supplied. The textured rim alone does not establish an adjustment mechanism. The source advertises a one-week lead time and custom sizes; confirm current delivery, custom specifications and accessories separately. No custom SKU is listed.
