功能

• A lens holder equipped with a lens centering mechanism and a focus adjustment mechanism to align the center of the lens with the laser beam.
• It can be used for collimating large diameter laser beams and laser focusing that requires precise positioning.
• There is also a 5-axis adjustment type (ALHN-5) with a lens tilt adjustment function, which is necessary for adjusting the wave front of the interferometer and the intensity distribution of the concentrated spot.
• The lens position can be moved back and forth by rotating the lens barrel with the lever to adjust the lens focus.
• The centering mechanism has a nut clamp and the focus adjustment has a screw clamp.
• In addition to single lenses, thick lenses and combination lens tubes with a thickness of 28 mm or less can be fixed.
• Rod type is also available.
• A centering lens holder (LHCM) without a focus adjustment function is also available.
• A centering lens holder (LHCM) for lenses of φ20 mm or less is available.
• * Use a special spacer (2 types) when fixing the lens inside the cylinder of the holder.
• * The length of the tube is 28 mm, so it will take a long time if you try to fix it only with the screw ring.
• * You can also change the position of the fixed lens by changing the position of the spacer and lens.
• * If the focal length of the lens increases, the focus range will be too narrow for adjustment.
• * Use the long hole of the mounting plate.
