Thorlabs NDUV13B Unmounted 25mm UV-Fused Silica Reflective ND Filter

The Thorlabs NDUV13B Unmounted 25mm UV-Fused Silica Reflective Neutral Density (ND) Filter is a high-quality optical filter designed for various applications that require UV light transmission and precise light attenuation. This unmounted filter boasts a 25mm diameter, making it compatible with a wide range of equipment.

The NDUV13B is crafted from UV-fused silica, a material renowned for its excellent UV transmittance and durability. This ensures consistent performance even under intense UV conditions. The filter's surface is reflective, which allows it to effectively reduce the intensity of light without absorbing it, thus minimizing any potential color cast.

The neutral density property of the filter enables it to attenuate light evenly across the visible and ultraviolet spectrum. This is achieved through the careful control of the filter's density, which is 1.3 optical density (OD) at 365nm. This specific density provides a versatile level of light reduction, suitable for many applications that require careful control of light levels.

The unmounted design of the NDUV13B offers flexibility in its use, allowing it to be easily integrated into various optical setups. It can be paired with a variety of filter mounts (sold separately) to suit specific equipment requirements.

In summary, the Thorlabs NDUV13B Unmounted 25mm UV-Fused Silica Reflective Neutral Density Filter is an essential tool for researchers, scientists, and hobbyists who work with UV light and need precise light attenuation. Its high-quality construction, versatile design, and specific light reduction properties make it an indispensable addition to any optical setup.

1. High Density: The 25um thickness of the filter provides a high optical density, reducing the intensity of light by a significant amount.

2. UV Transmission: This filter is designed to transmit UV light, making it suitable for applications where UV light is a crucial factor.

3. Durability: UV-Fused Silica is known for its durability and resistance to scratches, ensuring the filter maintains its performance over time.

4. Broadband Response: The NDUV13B filter offers a broadband response, which means it can be used across a wide range of wavelengths.

5. Reflective Design: The reflective design allows for the filter to be used in multiple setups without the need for additional mounting hardware.

1. No Mounting Option: Since it is unmounted, you will need to find or create a suitable mounting solution for your specific application.

2. Potential for Misplacement: Without a mount, there is a risk of losing the filter if not properly stored.

3. May Not Fit All Setups: Depending on the configuration of your optical setup, the filter may not fit without additional modifications.

The Thorlabs NDUV13B Unmounted 25um UV-Fused Silica Reflective ND Filter is a high-quality, durable option for applications requiring UV transmission and a high optical density. However, the lack of mounting options and potential fit issues may pose challenges for some users. If you can accommodate these potential drawbacks, this filter could be a valuable addition to your optical setup. If mounting is a concern, you may want to consider a similar filter that comes pre-mounted.
