Features

• It can be ***d in optical experiments as a light shield for stray light in lasers and as a screen for interferometers and schlierens.
• Since the BBP-2505B has a scale, it is convenient to adjust the height of the optical axis of the laser beam.
• BBP-3130B can block large areas.
• BBP-2505B and BBP-3130B come with a magnetic base for easy fixing of the light shielding plate.
• The BBP-200 is matted white so you can see a bright projection.
• Apply grid paper or black imitation paper to the blackout board according to the purpose.
• Use a square element holder (KMH-80) to hold the BBP-200.
• The base supplied with the BBP-2505B and BBP-3130B can be secured by post-clamping (PSC).
• The scale attached to the BBP-2505B is marked to approximately fit the height from the installation surface.
• * When using a high-power laser or a high-energy pulsed laser directly on a light shielding plate, it is dangerous if scattered light from the light shielding plate directly enters the eyes.
• * Be sure to wear protective eyewear.
