YIF-BA600-690S 25 mm Dia. Mounted Interference Bandpass Filter; t=3.5mm 607-680nm

The YIF-BA600-690S is a 25 mm diameter mounted interference bandpass filter, designed and manufactured by OptoSigma. This filter is specifically engineered to transmit light within the wavelength range of 607-680nm, making it ideal for applications that require narrow-band light transmission in this spectrum.

The filter is constructed with a base shape of a circle, a common form factor for optical components due to its symmetry and ease of integration into various systems. The filter's thickness is 3.5mm, providing sufficient structural integrity while minimizing optical distortions.

The YIF-BA600-690S features a unique coating on both the front and back surfaces, identified as 'opt yif-ba600-690s'. This coating is designed to enhance the filter's performance by reducing unwanted reflections and increasing transmission efficiency. The coating also provides protection to the filter's surface, reducing the risk of damage during handling and operation.

The filter's geometry is that of a thin lens, suggesting that it may have some light focusing capabilities, although this is not its primary function. The lens shape could be beneficial in certain applications where both filtering and focusing are required.
