Neutral density (ND) filters are optical components widely used in custom optics and photography to uniformly reduce the intensity of light without altering its color properties. These versatile filters play a crucial role in exposure control, enabling photographers and cinematographers to manage lighting conditions by adjusting shutter speed and aperture, allowing for creative effects like motion blur and shallow depth of field in bright environments. They are also valuable in balancing exposures in high-contrast scenes and facilitating long exposure and astrophotography. In custom optics, ND filters provide precise control over light intensity, finding applications in scientific and industrial settings where controlled exposure is critical. Custom ND filters can be tailored to specific optical systems, ensuring accurate light management for research, measurement, and imaging needs.

Optical windows are transparent or translucent components or materials that allow the passage of light while protecting sensitive optical systems or instruments from environmental factors. These windows are typically made from various materials with specific optical and mechanical properties to meet the requirements of different applications in optics and photonics.

Common materials used for optical windows include optical glasses (e.g., BK7, fused silica), sapphire, quartz, and various optical polymers. The choice of material depends on factors such as the required optical properties, spectral range, cost constraints, and environmental conditions in the intended application.
