The FA11903_TINA3-WW from Merit Lillie is an aspheric lens that covers an 8-14 µm spectral range. This lens is type-II, which means it has a refractive power that is substantially higher than type-I lenses. It is designed with a concentric 4-element design that allows for a wide field of view in one dimension even though it has a narrow field of view in the other. This makes it perfect for applications that require large amounts of light spread over a wide area.

This lens can be used in many applications, including scientific research, industrial machine vision, automotive safety, and telecommunication. It is often used in imaging systems and other spectroscopic instruments. The FA11903_TINA3-WW is a high-performance lens that offers uniform imaging in its wavelength range. Additionally, its high transmittance allows it to be used in low-light environments.

In terms of its working principle, this lens projects an image onto the image plane. Its refractive index is kept constant across its 4-element design, resulting in uniform imaging in its wavelength range. Additionally, its 4-element design allows it to possess a wide field of view in one direction while having a narrow field of view in the other direction. This makes it suitable for applications that require large amounts of light spread over a wide area.

The FA11903_TINA3-WW is resistant to damage, vibration, and thermal effects. It is also optically compensated for high-quality imaging. Its anti-reflective coating helps reduce flare and ghost images. Additionally, its 25 mm effective diameter and its angled face angle make it suitable for use in environments with limited space.

In conclusion, the FA11903_TINA3-WW is an aspheric lens from Merit Lillie that is suitable for many types of applications due to its 4-element design, which provides a wide field of view in one dimension while having a narrow field of view in the other. Its concentric design also allows for uniform imaging in its 8-14 µm spectral range. Additionally, its anti-reflective coating helps reduce flare and ghost images, and its resistance to damage, vibration, and thermals makes it suitable for use in difficult environments.
