UPH4 THORLABS Laser Beam Block Post Baseplate

Review THORLABS Laser Beam Block Lb1 On 1/2 Inch Post And Baseplate

The Thorlabs UPH4 Laser Beam Block LB1 1/2 Post Baseplate is a versatile and essential component for laser laboratory setups. This beam block is designed to provide efficient and reliable protection against stray or unwanted laser beams, ensuring a safer working environment.

The LB1 1/2 Post Baseplate is part of Thorlabs' UPH4 series of beam blocks, which are known for their high optical quality and durability. The beam block is made of borosilicate glass, a material that is resistant to thermal shock and has a high refractive index, making it an ideal choice for laser applications.

The LB1 1/2 Post Baseplate features a 1/2 post base that allows for easy mounting on standard laboratory posts. The post diameter is 19 mm, and the center height is 25 mm. The baseplate is also compatible with the Thorlabs LB1 Mounting Adapter, which enables the attachment of various accessories such as filters, polarizers, or prisms.

The UPH4 Laser Beam Block LB1 1/2 Post Baseplate has a high absorption coating on the backside, which effectively absorbs any reflected laser beams, reducing the risk of laser exposure. The front side of the beam block is left uncoated, allowing for maximum transmission of the laser beam.

The beam block has a square aperture with dimensions of 25 mm x 25 mm, providing ample space for most laser beams. The edges of the aperture are chamfered, which facilitates easy alignment of the laser beam.

The UPH4 Laser Beam Block LB1 1/2 Post Baseplate is an excellent choice for laboratory environments where laser safety is a priority. Its robust design, easy mounting, and high absorption coating make it a reliable and effective solution for protecting against stray laser beams. Additionally, its compatibility with various accessories allows for flexible customization to meet specific application requirements.
