기능

• This holder holds three lenses of any outer diameter size with nails.
• The lens core is designed to always be in the same position when the lens is held with three nails.
• It is a lens type and can be used for experiments such as trying out different kinds of lenses.
• The three claws of the holder touch the side of the lens and the spring pressure holds the lens.
• By pressing down the distance between the two levers, the three claws open, and when the force is relaxed, the three claws close.
• The position of the three claws can be fixed by tightening the clamp.
• * When holding a thin lens, the lens may fall down due to the spring holding force, and the lens may fall out of the holder.
• * Keep the lens slowly and carefully.
• * The lens core will slightly shift each time you hold the lens.
• * For precise measurement, use a lens holder (ALHN) with a crosshair mechanism.
