LB1187-A In Stock

The LB1187-A by ThorLabs is a premium quality bi-concave lens that has been expertly crafted from N-BK7 optical glass. The LB1187-A is a highly sought-after lens due to its versatile application in various finite imaging scenarios. It features an antireflection coating found on the surfaces that effectively reduces the amount of reflected light in the 350 - 700 nm range.

The LB1187-A is a perfect fit for situations where the object and image are on opposite sides of the lens, and the conjugate ratio falls within the range of 0.2 and 5. With a focal length of 100.0 mm, this lens is an ideal choice for imaging applications that are finite. N-BK7 optical glass is widely recognized as one of the most commonly used materials for producing high-quality optical components. It is often the preferred choice when the UV fused silica additional benefits are not required. The LB1187-A offers excellent transmission into the UV spectrum and a lower coefficient of thermal expansion. Additionally, this bi-concave lens is compact with a diameter of Ø1/2".
