Hot Item Mse Pro Round Continuously Variable Metallic Neutral Density Filters - Beat The Rush [CuhViFeY]

MSE PRO Round Continuously Variable ND Filters

The MSE PRO Round Continuously Variable ND Filters are designed to provide unparalleled flexibility and control in photographic and scientific applications. These filters offer a unique circularly variable neutral density feature, allowing for precise adjustment of light intensity without the need for multiple filters. With a gradual variation in optical density around a 270° circle, these filters provide seamless and convenient attenuation control by simply rotating them.

Key Features and Specifications

Featuring a thin Ni-Cr-Fe film, these ND filters are not only durable and resistant to moderate laser energy but also act as variable beamsplitters. The filters come with BK7 substrates for general laboratory use or UV fused silica substrates for maximum thermal stability, ensuring optimal performance across a wide spectral range. The coatings are optimized for 400-700nm but can operate effectively from 400-1100nm with minimal losses. Here are some of the key specifications:

• Material: BK7 fine annealed or UV fused silica
• Outside Diameter: φ50±0.25
• Center Hole Diameter: 8±0.25
• Clear Aperture: >80% diameter
• Linearity of Optical Density: ±5% at 632.8nm
• Coating: S1:Ni-Cr-Fe, S2: Broadband AR coated, R_ave<0.5% for 420-675nm at 0-15º incidence
• Relative Density Range: 0.0-1.0

Applications and Benefits

These versatile filters are ideal for a wide range of applications, including photography, scientific research, and industrial processes. By allowing for precise control of light intensity, these filters can help achieve the perfect exposure and depth of field, making them an essential tool for photographers and videographers. In scientific research, the ability to adjust light intensity without altering the beam's path is invaluable for experiments requiring precise control over optical density. With MSE Supplies, you can expect exceptional quality, customization options, and bulk order capabilities, making these filters a practical choice for both professionals and hobbyists alike.
