A Long Pass Filter (LPF) is an optical component that allows long-wavelength light above a specific wavelength to pass through while blocking short-wavelength light. The core function of the LP1430nm Long Pass Filter is to block short-wavelength light below 1430nm and only allow long-wavelength light at 1430nm and above to pass through. Its design principle is similar to the LPF600nm and 525nm Long Pass Filters mentioned in the search results, both achieving spectral selectivity through multilayer coating technology.

Key Optical Parameters (Based on Similar Products)

• Blocking Wavelength Range: Typically capable of effectively blocking short-wavelength light from 200nm to 1420nm (specific blocking depth should refer to product specifications, such as OD4 or OD5 level; higher OD values indicate stronger blocking performance).
• Transmission Wavelength Range: 1430nm and above (e.g., up to 1700nm or beyond, depending on substrate material and coating technology).
• Transmittance: Usually ≥90% in the target long-wavelength band, with high-transmission coating technology potentially increasing it to over 95%.
