• Material: 6061-T6 aluminium alloy
• Convenient, fast and accurate adjustment;
• A slight adjustment for post height is only required when the post angle does not change;
• Rotating the hand wheel for 360 degrees can raise the optical elements for 1 mm.

     The PSC28 series spiral height adjusters are used to adjust the height of optical elements. Rotating the hand wheel for 360 degrees can raise the optical elements for 1 mm, delivering convenient, fast and accurate height adjustment. After adjusting to an appropriate height, a locking hand wheel is used to lock optical elements and connect them to optical tables. A slight adjustment for post height is only required when the post angle remains unchanged. First fix the lifting rod seat in the selected position in optical paths, insert the post into the center hole on the lifting rod seat, and lock the post firmly with the locking hand wheel after adjusting to an appropriate height by rough adjustment. Adjust the lifting parts to an expected height and lock them with the locking hand wheel to finish the adjustment.
