Q: What is the transmission efficiency of the LPF series longpass filters?
A: Our standard LPF series optical longpass filters offer a high transmission rate of over 85% average in their respective transmission bands, ensuring minimal signal attenuation.
Q: What does the "Cut-off depth >OD4" parameter signify?
A: Optical Density 4 (OD4) indicates that the filter blocks unwanted wavelengths in the cut-off range to a transmission level of less than 0.01%, providing superior signal-to-noise ratios.
Q: Can I request a longpass filter with a custom cut-off wavelength?
A: Yes. While the table lists our current stock items, we can custom-manufacture filters with specific cut-off points, dimensions, or substrates tailored to your requirements.
Q: Are these longpass filters suitable for visible and near-infrared (NIR) applications?
A: Absolutely. Our LPF line covers cut-off ranges spanning from 200nm up to 1060nm, with transmission ranges extending up to 1800nm, making them ideal for UV, visible, and NIR applications.
Q: How do I check pricing and lead time for stock or custom filters?
A: You can easily click the "contact us" link on our page to submit an inquiry. Our technical sales team will promptly reply with pricing, availability, and lead times.
