ANDOVER

ANDOVER is a brand that has been around since 1976 and is based in Salem, NH, USA. It is one of the leading international manufacturers of high-quality optical coatings and optical filters [1]. The brand specializes in producing filters that can separate transmitted light and reflected light based on the cutoff wavelength [2]. The products of ANDOVER are known for their quality and stability, with patented technologies that can prevent peak wavelength drift over time

ANDOVER products are used in many applications, including spectroscopy, astronomy, and biomedical research [1]. Some of the products that ANDOVER offers include:

• Optical filters: ANDOVER produces various types of optical filters, including bandpass filters, longpass filters, shortpass filters, notch filters, and dichroic filters [1]. These filters are designed to transmit or reflect light within specific wavelength ranges, making them useful in many different applications.

• Neutral density filters: ANDOVER produces neutral density filters that can attenuate light without changing its spectral characteristics [1]. These filters are useful in applications where the light intensity needs to be reduced, such as in photography or laser systems.

• Coated optics: ANDOVER produces coated optics, including mirrors, beamsplitters, and lenses [1]. These optics are coated with special materials that can enhance their reflectivity or transmissivity, making them useful in many different applications.

In summary, ANDOVER is a brand that specializes in producing high-quality optical filters and coatings. Its products are known for their stability and patented technologies that prevent peak wavelength drift over time. ANDOVER products are used in many different applications, including spectroscopy, astronomy, and biomedical research
