39-384 25 mm Dia. Mounted Hard Coated OD 4.0 Notch Filter 1030nm

The 39-384 is a 25 mm diameter notch filter, designed and manufactured by Edmund Optics, a leading provider of optical components. This filter is specifically designed for use at a central wavelength of 1030nm, making it ideal for applications that require precise filtering in this spectral region.

The filter is mounted and hard coated, with a thickness of 5mm, providing robustness and durability. The hard coating on both the front and back surfaces of the filter enhances its resistance to wear and tear, ensuring a long lifespan even under demanding conditions.

The filter's geometry is defined by its 25mm diameter, which is a common size for many optical systems due to its balance between compactness and light-gathering capability. This diameter is also compatible with a wide range of optical mounts and holders, providing flexibility in system design.

The physical data of the filter includes a center wavelength of 1030nm, which is the specific wavelength that the filter is designed to pass. This makes it ideal for applications such as laser spectroscopy, where precise wavelength selection is critical.

The coating on the filter is a multi-layer dielectric coating, specifically the EDm 39-383 coating. This coating is designed to provide high transmission at the desired wavelength, while also rejecting unwanted out-of-band light. The coating is applied to both the front and back surfaces of the filter, ensuring optimal performance from both sides.

The shape of the filter is a thin lens, which is a common shape for optical filters due to its compactness and ease of integration into optical systems. This shape also minimizes optical aberrations, ensuring high-quality performance.
