39-311 12.5 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 1450nm

The 39-311 is a Bandpass Filter with a diameter of 12.5 mm, sourced from the reputable optical vendor, Edmund Optics. This filter is specifically designed for a central wavelength of 1450nm, making it ideal for applications that require precise filtering within this spectrum.

The filter is hard coated on both the front and back surfaces, denoted as 'edm 39-311', which enhances its durability and resistance to wear and tear. This coating also aids in maintaining the filter's performance over time, ensuring consistent results in your optical experiments or systems.

The physical data of the filter includes a cut-on wavelength of 1445nm and a cut-off wavelength of 1455nm, providing a narrow 10nm bandwidth. This makes the filter highly selective, allowing only light within this specific range to pass through.

The filter has a thickness of 3.5 mm and is shaped as a thin lens. This geometry, combined with its small diameter, makes it suitable for use in compact optical systems where space is at a premium.

According to the vendor's information, the filter is currently in stock, ensuring quick delivery and minimal lead times. The filter's catalog number, 39-311, can be used to reference it in further communications with the vendor or when placing an order.
