Porro Binoculars WP48 10x50 Green
The WP48 10x50 Green is a non-waterproof porro prism binocular with a 50 mm objective, built for brands that need a high-light-gathering model without nitrogen filling. It shares the same optical system across the WP48 series, so a buyer can run multiple magnification variants off one proven platform. Standard build uses BK7 prisms and green+blue coating, with fold-down eyecups and a centre focus wheel. It is tripod adaptable and available in full black or green+black housing.

Key Benefits
10x magnification with a 50 mm objective gathers more light than smaller models, improving visibility in low light
Porro Binoculars WP48 10x50 Green: Porro prism layout provides a wider field of view and better depth perception than roof prisms at the same size
Fold-down eyecups allow compact storage and easy use with or without glasses
Tripod adaptable through a standard adapter thread, so the same SKU serves hand-held and static observation
Shared optical platform across the WP48 series reduces tooling cost when expanding the product line
Green+blue coating reduces glare and improves contrast in bright conditions
Where It Is Used
Birdwatching in low light conditions such as dawn or dusk
Hiking and nature observation where a larger objective helps in dim forest light
Outdoor education and school programs where durability and light gathering are priorities
Retail chains building a mid-tier house brand with a focus on value and performance
E-commerce sellers who need a non-waterproof model with a clear IPX7 disclaimer
Who It Is For

- Importers replacing a non-waterproof 50 mm model that is currently in stock
- Amazon and e-commerce sellers who need a model with strong light-gathering but no waterproof claim
- Outdoor and nature retail chains building a value-focused product line
- Buyers who already stock other WP48 models and want to expand with a 10x50 variant
Problems It Solves
The cost of developing a new optical system when only the magnification or housing needs to change
Uncertain performance in low light due to a small objective diameter
Inconsistent image quality when switching between different non-waterproof models
Eyecup design that does not accommodate users who wear glasses
Lack of tripod adaptability in models meant for long observation sessions

- WP48 12x50
- The 12x50 offers higher magnification but has a narrower field of view and is harder to hold steady; the 10x50 is a balanced mid-range option
- Waterproof roof models such as the WD67 10x42
- The WD67 is nitrogen filled and IPX7 rated; the WP48 is not and will fog in rain or sudden temperature change
- Non-waterproof roof models such as the SRB03 10x42
- The SRB03 has a roof prism and is lighter; the WP48 has a porro prism and gathers more light but is bulkier
