# Custom PIR Lens Development Process | Efficient & High-Performance Solution

✨ Custom Fresnel PIR Lenses, One-stop Optical Solution

In human body infrared sensing and intelligent sensing industries, Fresnel PIR lenses act as the “eyes” of detectors. The optical design and mold precision of lenses directly determine sensing distance, detection angle and overall equipment stability.

With years of experience in infrared optical components, Xinyongcheng Optoelectronics has built a full in-house chain for **PIR lens development and mold self-development**. We deliver customized projects efficiently from requirement discussion to sample delivery.

## 🔍 PIR Lens Development Process: Two Core Advantages: High Matching & Short Lead Time

Features of our development workflow:

1. The matching rate between design simulation and actual product performance exceeds 95%;

2. Short delivery cycle: only 35 days from order placement to sample output, compared with the industry average of 50–60 days.

📋 Workflow sequence:

Requirement Communication → Structural & Optical Communication → Pre-design Performance Analysis → Customer Order → Optical Design & Simulation → Interference Analysis → Processing Feasibility Evaluation → Produce Processing Drawings

We fully align with customers on application scenarios, sensing specifications and assembly constraints at the early stage and carry out pre-performance evaluation. Optical simulation is used to model light paths in advance to eliminate optical interference and assess mold manufacturability.

This ensures high consistency between simulation results and mass-produced parts, reduces repeated sample revisions and shortens your project timeline.

## 🛠️ Self-developed PIR Lens Mold Process: In-house Mold Workshop for Precision Control

Molds are the foundation of lens quality. Xinyongcheng Optoelectronics independently develops all molds without outsourcing, to guarantee high precision of optical profiles.

Workflow sequence:

Order Initiation → DFM Analysis → 2D & 3D Design → Material Procurement → Mold Processing → Mold Assembly → Test Mold → Customer Confirmation

Mold processing covers multiple processes including CNC Machining, Milling & Grinding Machine Processing, Wire Cutting Processing, EDM Machining, Polishing and Data Detection. Multi-process collaboration strictly controls the precision of optical cavity surfaces, ensuring optical consistency of molded lenses.
