The 20BPF70-650 is a Bandpass Filter from MKS/Newport, designed with a square shape of 50.8 x 50.8 mm and a thickness of 3.3274 mm. This filter is specifically designed for use in the 650nm wavelength range, with a cut-on wavelength of 615nm and a cut-off wavelength of 685nm. The filter's geometry is defined by its width, height, and thickness, making it suitable for various optical applications.
The 20BPF70-650 features a New BPF10-650 coating on both the front and back surfaces, which is a unique characteristic of this filter. This coating enhances its performance and durability, making it a reliable choice for optical systems that require a bandpass filter in the 650nm range.
The filter's physical data, including the cut-on, cut-off, and central wavelength (CWL), are precisely controlled during manufacturing to ensure high-quality performance. The filter's shape is designed as a Thin Lens, which is ideal for applications that require minimal optical distortion.
