( Brand: Thorlabs ), ( Part Type: Filter Mount ), ( Manufacturer Part Number: ND30A )
The Thorlabs ND30A Reflective 25 ND Filter is a high-quality optical filter designed for use in various applications where light intensity reduction is necessary. This filter features a 25 ND (Neutral Density) density, which means it reduces the light intensity by a factor of 100,000. This is particularly useful in situations where the intensity of the light source is too high and needs to be attenuated to prevent damage to sensitive equipment or to achieve desired exposure levels.
The ND30A filter is a reflective type, which means it works by reflecting a portion of the incoming light. This design has several advantages over absorptive filters, including reduced heat generation and longer filter life due to less absorption of light. The filter has an SM1 threaded mount, which is a standard thread size used in the optics industry, making it compatible with a wide range of optical equipment.
The filter's 3.0 density is measured using the optical density (OD) scale, where OD 1.0 reduces light intensity by a factor of 10, OD 2.0 by a factor of 100, and so on. The ND30A's OD 3.0 density reduces light intensity by a factor of 100,000, making it one of the densest filters available. This high density makes it ideal for use in high-power applications, such as laser safety and high-intensity illumination.
The Thorlabs ND30A Reflective 25 ND Filter is made of high-quality materials, ensuring excellent optical performance and longevity. It is designed to provide consistent performance over time, with minimal changes in transmission or absorption. The filter is also coated to minimize reflection and scattering, further ensuring optimal performance.
In summary, the Thorlabs ND30A Reflective 25 ND Filter is a high-density, high-performance optical filter that is ideal for use in high-power applications. Its SM1 threaded mount makes it compatible with a wide range of equipment, and its reflective design ensures reduced heat generation and longer filter life. With its high optical density, this filter is an essential tool for scientists, engineers, and technicians working with high-intensity light sources.
